Main ideas
Post-quantum migration is a planning deadline, not a Q-Day prediction · Architecture changes which secrets a quantum computer can threaten · Open source is not the same as reviewed, and defenders need AI tools they can run themselves
Alex Pruden writes about quantum computing, post-quantum cryptography and cybersecurity, focusing on what technical developments mean for digital assets and other systems that depend on cryptography.
Their posts urge organizations to prepare for the transition before a quantum computer can break today’s encryption.
They explain why the risk differs by hardware design, what real migration tests can reveal, and why open code still needs active security review.
The posts also connect this work to Project Eleven, which they describe as building post-quantum key management for digital assets.
Pruden turns technical developments into specific security consequences without treating estimates as certainties.
In comparing quantum resource estimates, they explain why a smaller, slower machine could threaten exposed, long-lived keys even if it could not attack a live transaction.
A neutral-atom primer makes unfamiliar hardware easier to picture and links its design to the challenge of scaling.
Other posts apply the same practical lens to AI-assisted code audits and Cloudflare’s test of post-quantum signatures in DNSSEC: implementation can uncover risks that a simple algorithm swap would miss.
Follow this work for clear explanations of how quantum and cybersecurity developments affect real systems and what preparation may be needed before the technology is fully mature.
Alex Pruden's recurring argument is that post-quantum cryptography is near-term operational work for anyone holding or securing digital assets, not a distant Q-Day forecast.

Across seven long-form LinkedIn posts, Pruden reads new quantum resource estimates, hardware designs, government funding, vendor platforms and deployment tests as signs that the cost of breaking today's cryptography is falling—and that migration lead time matters more than the arrival date of a working quantum computer.
A second thread is who gets to use AI for security: open code is not automatically reviewed, and defenders need inspectable, self-hosted tools rather than access controlled by closed labs.
The posts pair technical explainers with explicit calls to action for Project Eleven, the company Pruden represents in the material.
Post-quantum migration is a planning deadline, not a Q-Day prediction
Alex Pruden argues that falling estimates for breaking elliptic-curve cryptography change the decision for custodians, exchanges and protocol teams, even though no cryptographically relevant quantum computer exists yet.
Read more
The case is strongest for keys that are already exposed or must stay secret for years: neither can wait for a fast machine.
Pruden sees independent teams converging on compatible numbers as the real signal.
The resource bar is lower than the field believed a year earlier, so migration planning should start now, not after a breakthrough.
In the Bitcoin risk post, Alex Pruden compares IonQ, Google and Oratomic estimates for recovering a private key from Bitcoin's elliptic-curve signatures.
IonQ's trapped-ion design is estimated at about 20,000 physical qubits but roughly 26 days per attempt; Google modeled under 500,000 physical qubits running in minutes.
Pruden notes that the largest fault-tolerant trapped-ion demonstrations today are around 100 physical qubits, and calls IonQ's link to a stated 2028 roadmap a concrete, accountable claim—not a fait accompli.
The same urgency runs from a specific hardware estimate to government and vendor investment: both suggest an industrializing ecosystem is setting the timeline.
Architecture changes which secrets a quantum computer can threaten
Alex Pruden's posts distinguish quantum machines by architecture, not just qubit count.
Read more
Different modalities trade size for speed, and that tradeoff determines whether a machine could attack a live transaction or only a long-lived exposed key. Pruden consistently explains why a threat is narrow or broad before telling readers what to do about it.
The Bitcoin risk post contrasts superconducting, trapped-ion and neutral-atom approaches.
A machine that finishes in minutes could target a transaction while it is still being confirmed; one that takes 26 days cannot, so it threatens static, already-exposed balances, with Satoshi's early coins the most famous case.
The neutral-atom primer explains the design: atoms trapped in laser beams, moved by sliding a beam, linked by flashing light and read by camera.
Because atoms can be physically moved, any two can become neighbors; scaling comes from splitting laser light rather than fabricating bigger chips.
Open source is not the same as reviewed, and defenders need AI tools they can run themselves
Alex Pruden argues that publishing code does not mean anyone has examined it, and that human reviewers alone cannot continuously scrutinize everything published.
Read more
The Coldcard hack illustrates the gap between transparency and review. Pruden also argues that closed-model safety guardrails constrain legitimate defenders while attackers face no equivalent constraint, making open-weight models essential for independent security testing that defenders can inspect and direct at their own systems.
The Coldcard firmware flaw sat in public, open-source code for years before attackers used it to steal more than $100 million.
After the hack, security researchers used AI-assisted tools to audit hundreds of open-source Bitcoin projects and reported nearly 5,000 findings in about a day, including dozens of critical issues not previously reported.
Pruden also quotes Coinkite's CEO saying they believe AI may have played a role in finding the flaw; that remains the CEO's claim, not an independently established fact.
Production money and platform coalitions are the real timeline signals
Alex Pruden sees capital flowing to foundries, supply chains and shared software layers as more informative than any single lab result.
Read more
A technology preparing to scale, Pruden argues, looks like production infrastructure and industry coordination, not a proof-of-concept demonstration. For cryptographic infrastructure operators, the deadline is when ecosystem coordination must be complete, minus migration lead time.
One post breaks down $2.013 billion in CHIPS Act incentives for nine quantum companies, including $1 billion for IBM to build a quantum-grade superconducting wafer foundry and $375 million for GlobalFoundries, with the rest going to seven quantum computing firms.
Another covers NVIDIA's CUDA-Q Logical layer and roughly twenty hardware partners.
It reports Fermilab cutting fault-tolerant algorithm development from five months to three weeks, and one partner modeling 1,000 logical qubits at 150,000 physical qubits, roughly ten times fewer than earlier estimates.
Pruden notes that no fault-tolerant machine exists today.
Migration is an integration problem: test it and watch what breaks
Alex Pruden favors deployed tests over claims that post-quantum migration amounts to swapping signatures.
Read more
The priority is to test the null hypothesis that everything continues as normal and take failures seriously: integration problems are where the real work and hidden risks lie.
In the Cloudflare post, Alex Pruden highlights Bas Westerbaan and Cloudflare implementing ML-DSA-44 in DNSSEC and deploying it in test zones, with Cloudflare's 1.1.1.1 resolver validating the post-quantum signatures.
Pruden says the test surfaced issues introduced by the change and that their gut feeling is this may be the tip of the iceberg.
Cloudflare did the implementation; Pruden offers the interpretation and tip-of-the-iceberg judgment.
Answers the question 'Do falling qubit estimates actually change the risk to Bitcoin?' and distinguishes breaking live transactions from cracking already-exposed keys for newcomers.

Alex Pruden compares three estimates of the quantum resources needed to break Bitcoin’s elliptic-curve cryptography.
Google modeled a superconducting machine requiring fewer than 500,000 physical qubits to run the attack in minutes.
IonQ’s trapped-ion design needs about 20,000 physical qubits but takes roughly 26 days per attempt; Oratomic’s neutral-atom estimate is close to IonQ’s.
The key point for readers: architecture changes the threat.
A fast machine could target a transaction while it is being confirmed, while a slower one threatens long-lived exposed keys, such as addresses whose public keys are already visible on-chain.
These are engineering estimates for machines that do not yet exist, not a Q-Day prediction.
For brands planning a campaign
A strong anchor for an institutional explainer on why post-quantum migration starts with long-lived secrets and exposed keys, with architecture tradeoffs as the technical hook.
Answers 'Why is AI access a security question, not just a capability question?' and helps newcomers understand the defender-attacker asymmetry.
Read more
Alex Pruden uses a Coldcard firmware flaw that cost Bitcoin holders tens of millions of dollars to ask who gets to use AI to find security flaws first.
Coinkite shipped a fix, and its CEO suggested AI may have helped find the flaw.
The argument is structural: closed labs apply guardrails that also slow legitimate defenders, while attackers face no such constraints.
They connect this asymmetry to post-quantum migration, a larger engineering effort with more opportunities for overlooked details.
For brands planning a campaign
Useful for a webinar or explainer on AI-assisted security review, open-weight tooling, and the need to build adversarial testing into migration projects.

Alex Pruden breaks down $2.013 billion in CHIPS Act incentives for nine quantum companies: IBM gets $1B for a quantum-grade superconducting wafer foundry, GlobalFoundries gets $375M for a multi-architecture foundry, and the remaining $638M goes to Atom Computing, Diraq, D-Wave, Infleqtion, PsiQuantum, Quantinuum, and Rigetti.
The funding goes to production, foundries, and supply chains rather than research labs—a sign, in their reading, of a technology preparing to scale.
The practical reframing: the relevant migration deadline is not Q-Day but the point when ecosystem coordination must be complete.
For brands planning a campaign
A strong opening for a policy-to-practice explainer for institutional clients: funding signals are a reason to start migration planning now, not wait for a working quantum computer.
Answers 'How do neutral-atom quantum computers work, and why should a non-specialist care?' The set’s most accessible technical primer.
Read more
Alex Pruden explains neutral-atom quantum computing with a simple analogy: atoms held by laser beams on a grid, moved by sliding a beam, linked by flashing light, and read by camera.
The design stands out because atoms can be physically moved so any two can become neighbors, every atom is identical and replaceable, and scaling comes from splitting laser light rather than fabricating bigger chips.
The post cites Atom Computing's first error correction and commercial machine with Microsoft, QuEra's 2028 fault-tolerant system with AWS, and a result suggesting roughly 10,000 atoms could run the algorithm that breaks today's encryption.
These machines will not hijack live connections, but they can crack long-lived secrets.

Alex Pruden argues that open source is not the same as reviewed, citing the Coldcard hack: the firmware had been publicly readable for years, but attackers used a flaw to steal more than $100 million before anyone caught it.
After the hack, researchers used AI-assisted tools to audit hundreds of open-source Bitcoin projects and found nearly 5,000 issues in about a day, including dozens of critical ones previously unreported.
Their conclusion: transparency needs continuous scrutiny at the scale of everything published, and defenders need open-weight models they can run themselves rather than gatekept tools.

Alex Pruden covers NVIDIA's expansion of CUDA-Q with a fault-tolerant layer, CUDA-Q Logical, and roughly twenty quantum hardware companies behind it, including Google, IBM, IonQ, and Quantinuum.
A cryptographically relevant quantum computer is not the result of one breakthrough but a stack: physical qubits, error correction, logical operations, real-time decoding, and sustained runtime.
Many middle layers are classical-computing problems.
The post cites Fermilab cutting fault-tolerant algorithm development from five months to three weeks and one partner modeling 1,000 logical qubits at 150,000 physical qubits, roughly ten times fewer than earlier estimates.
No fault-tolerant machine exists yet, but the signal is industrialization.

Useful for framing post-quantum readiness as an ecosystem and integration problem, not a single-lab race.
Answers 'What does a real post-quantum migration look like beyond the algorithm?' and shows why the transition is not a simple signature swap.

Alex Pruden highlights Cloudflare's implementation of ML-DSA-44 in DNSSEC and deployment in test zones, with Cloudflare's 1.1.1.1 resolver validating the post-quantum signatures.
This tests the null hypothesis that swapping in post-quantum signatures lets everything continue as normal—and finds issues introduced by the change.
They say their gut feeling is that this may be the tip of the iceberg.

Post-quantum migration urgency for digital assets
Alex Pruden's strongest recurring argument is that advances in quantum computing are lowering the estimated cost of breaking cryptographic systems, so digital asset custodians, exchanges, and protocol teams should move to post-quantum cryptography before long-lived secrets are exposed.
Read more
In one post, they compare IonQ, Google, and Oratomic resource estimates for breaking Bitcoin's elliptic-curve cryptography and distinguish machines that could attack a live transaction from slower machines that threaten already-visible public keys.

A neutral-atom primer uses an accessible analogy—atoms trapped in laser beams, moved and linked, then read by camera—to explain a leading fault-tolerant design and its scalability advantages.
Another post explains NVIDIA's CUDA-Q Logical layer as an attempt to solve the classical-compute middle of the stack, including error correction, decoding, and hardware co-design.
In the Bitcoin risk post, they contrast superconducting, trapped-ion, and neutral-atom approaches by physical qubit count and runtime.
Uses analogies, step-by-step explanations, and architecture comparisons to make specialized hardware legible.
The posts distinguish published models and benchmarks from a working fault-tolerant machine.
For brands planning a campaign
A brand can evaluate this for technical explainers that help institutional audiences understand architecture tradeoffs without vendor hype. It is less suited to product-led or short-clip formats.
AI-assisted security auditing and open-source review
Two posts examine the Coldcard Bitcoin wallet hack and its aftermath.
Read more
Alex Pruden argues that open-source code is not automatically reviewed, that a firmware flaw in a widely trusted wallet went unnoticed for years, and that AI-assisted audits of hundreds of open-source Bitcoin projects produced nearly 5,000 findings in about a day.
The posts also argue that closed-model safety guardrails can leave defenders less equipped than attackers and that open-weight models are needed for independent security testing.
They tie the same argument to the complexity of post-quantum migration.
Uses a real incident and its aftermath to make a structural argument rather than a product pitch.
Ask for the underlying evidence supporting the $100 million-plus figure and the 5,000 findings.

Alex Pruden highlights the value of testing the assumption that replacing signatures lets everything continue as normal and notes that the test surfaced issues that may be only the start. This offers a direct example of implementation experience rather than a high-level call to migrate.
Treats a deployed test as evidence and focuses on hidden integration problems.

One post details $2.013 billion in CHIPS Act incentives for nine quantum companies, including $1 billion for IBM to build a quantum-grade superconducting wafer foundry and $375 million for GlobalFoundries.
Another covers NVIDIA's CUDA-Q Logical platform and roughly twenty hardware partners, reading it as the dominant classical-compute company placing itself in the middle of the quantum stack.
The posts argue that production-side spending and industry coordination matter more than a single lab breakthrough.
Interprets capital allocation, foundry investment, and partner coalitions as leading indicators.
The posts note that funding and benchmarks do not equal a fault-tolerant quantum computer.
For brands planning a campaign
Useful for explaining why post-quantum preparation is becoming an ecosystem coordination problem. A brand can build a session around reading investment signals rather than speculating about dates.

Their posts cover quantum computing, post-quantum cryptography and digital-asset security, making them a plausible topical fit for campaigns educating institutional audiences about post-quantum topics.
Before placement, request recent LinkedIn audience demographics and any audience survey covering job function, seniority and industry, plus results for comparable post-quantum or quantum-risk posts.
If those are unavailable, treat this as a narrow, topic-aligned audience whose professional relevance still needs verification, and validate through a paid test before committing to a webinar or explainer series.
Alex Pruden's LinkedIn posts contain no sponsorship, sponsored-content, or partnership offer.
Read more
All seven are original commentary on quantum computing, post-quantum cryptography, and digital-asset security, published on LinkedIn between late May and mid-September 2026.
Several close with a mention of Project Eleven and a link to its website, promoting the company they write for rather than an advertising format available to outside brands.
Their posts include no media kit, rate card, sponsorship policy, audience demographic breakdown, booking page, or contact route.
Buyers would need to propose a campaign directly and ask about terms, deliverables, and disclosure practices before budgeting.
An educational format, such as a co-produced explainer series or webinar on post-quantum migration, is the closest fit with the work already visible.
Brief: a digital asset security company wants to educate institutional clients on post-quantum cryptography through a webinar or explainer series.
Read more
Alex Pruden is a strong subject-matter fit: every post here addresses the brief.
The standout is a comparison of IonQ, Google, and Oratomic resource estimates for breaking Bitcoin's elliptic-curve cryptography.
It distinguishes a fast machine that could attack a transaction while it is still confirming from a slower machine that threatens exposed public keys, and states plainly that no such machine exists yet.
That is the migration argument institutional clients need to understand before buying anything.
Other posts include a plain-language primer on neutral-atom hardware; an analysis of NVIDIA's CUDA-Q expansion as the classical-compute middle of the fault-tolerance stack; a breakdown of the $2.013 billion in CHIPS Act awards to foundries and supply chains rather than labs; and a post on Cloudflare's ML-DSA-44 DNSSEC test zones that frames migration as an engineering problem, not a signature swap.
Two Coldcard posts offer an audit angle: open source does not mean reviewed, and AI-assisted tooling found nearly 5,000 issues across hundreds of Bitcoin projects in about a day.
The teaching method is readily adaptable: a sharp opening claim, technical context, a numbered or TL;DR recap, and a practical implication.
Format fit is less certain: the posts offer no sponsorship format, rate card, media kit, booking page, or inquiry route, so a campaign would need to be proposed and negotiated from scratch.
The profile shows 2,038 followers but no seniority, function, industry, reach, or engagement data.
Ask for an audience test before committing.
Pruden writes for Project Eleven, which builds post-quantum key management for digital assets, putting a digital asset security sponsor alongside the writer's employer commercially; disclose and agree on that relationship in writing.
Overall, this is a subject and format fit, pending an audience test and conflict clearance.
When to choose a specialist
Brief: a consumer fintech app wants short-form video from a creator to drive mass-market app installs, with success judged on reach and conversion and delivery due on a short deadline.
Read more
Alex Pruden's posts offer little support for that brief.
All seven are long-form analytical commentary on LinkedIn, aimed at people already responsible for cryptographic infrastructure.
The subjects—quantum resource estimates, hardware modalities, wafer-fab funding, wallet firmware flaws, and a DNSSEC test deployment—are narrow and technical.
There is no consumer money content, guidance on what individuals should do with their accounts, or reason for a general audience to install an app.
Reach is also unproven: the profile lists 2,038 followers but no demographics, reach, or engagement data.
The posts provide no basis for forecasting a campaign whose success depends on scale.
Nor do they establish a reliable cadence: publication dates are inconsistent, leaving no verified posting rhythm to plan around.
The commercial structure is another mismatch.
No sponsorship offer, format, or contact route is published, while recurring calls to action for Project Eleven make the content read as company positioning rather than an open slot for a consumer brand.
Before considering a paid test, ask for a proposed format, audience evidence, and delivery schedule; the current record does not establish any of them.
A worked campaign example
A campaign to educate institutional clients on post-quantum cryptography could take the form of a three-part explainer series plus one live webinar, built from material already in Alex Pruden's posts.
Frame the series around the posts' central reframe: the deadline is when ecosystem coordination must be complete, not when a working quantum computer arrives.
Episode one would explain what falling qubit estimates mean for a custodian's holdings, using the side-by-side comparison of Google's superconducting model at under 500,000 physical qubits running in minutes, IonQ's trapped-ion design at about 20,000 physical qubits and roughly 26 days per attempt, and Oratomic's neutral-atom estimate close to IonQ's.
The teaching point is the distinction between an attack on a transaction in flight and one on keys already visible on-chain.
Ask attendees to list which of their own keys are exposed today.
Episode two would show why migration is not a signature swap, drawing on Cloudflare's ML-DSA-44 DNSSEC test zones, where the 1.1.1.1 resolver validates the signatures, and the CUDA-Q post's stack framing: physical qubits, error correction, logical operations, real-time decoding, and sustained runtime.
Include the figures from that post: five months cut to three weeks for fault-tolerant algorithm development, and one partner's model of 1,000 logical qubits at 150,000 physical qubits.
Episode three would address who audits the migration, using the Coldcard incident and the AI-assisted audit that produced nearly 5,000 findings in about a day to make the case for tooling defenders can run themselves.
Each episode could have a short companion post following the pattern across Pruden's posts: a sharp claim, technical context, a numbered recap, and a practical implication.
The live webinar could give attendees a two-page migration readiness checklist and walk them through it: which keys are exposed now, which systems depend on the cryptography being replaced, who signs off on the migration, and how often independent audit happens.
Publish a completed example and a blank version for viewers to use without attending.
A practical implication followed by a link, as in Pruden's usual closing, gives the sponsor a natural end slot without requiring a product claim beyond published facts.
Before booking, agree in writing on deliverables and fee, since no rate card or inquiry route exists; disclosure of the Project Eleven relationship and whether the sponsor accepts a writer whose employer occupies adjacent commercial ground; and a measured test after the first episode to check whether the audience includes the institutional buyers this campaign targets.
Verify the headline numbers before broadcast: the qubit estimates, funding figures, and loss amount come from the posts and have not been independently checked.
Choose Bryant D Nielson when the deliverable is a governance or board-facing programme rather than a technology explainer.
Read more
The posts work through a question an institutional client will actually ask: which information has to stay confidential for 7, 10, 15 or 20 years, and is therefore already exposed under a harvest-now, decrypt-later threat.
The material names an inventory process covering which critical systems hold long-lived information, what cryptography protects it, who owns the system, whether exposure already exists, whether crypto agility has been demonstrated, and whether a remediation date has been set.
It describes a scoring approach whose pillars include data longevity and exposure management and proven migration readiness, and specifies what the board should receive instead of another quantum presentation: the current risk score, inventory coverage, top exposures, vendor gaps and management actions.
The second post extends that into an in-person convening in Arlington, Virginia on 10 March 2027 and lists the questions boards ask, including what not to spend money on yet.
For a webinar designed to move a risk committee, this is the closer match.
The tradeoff is depth on the technology.
Neither post explains how a quantum machine works or walks through resource estimates, so a technical audience seeking the migration case would get the governance wrapper without the underlying argument.
The content is framework-led and repeatedly points to a named standard, QCI-QS1 v2.3, which the posts describe and promote; a buyer wanting neutral education would have to strip out that framing.
There are no digital-asset or custody specifics, including Bitcoin, wallet or key-management examples.
Ask for audience size, sponsorship availability and a booking route before moving forward.
Lee when a campaign needs ecosystem and vendor mapping rather than the migration argument.
One post recaps a European quantum conference and lays out the supply side: the shift from research toward infrastructure, fragmentation, skills, supply chains and commercialisation, with named roles for IBM, AQT and IQM, plus a survey of end-user experimentation across finance, healthcare, materials, energy, telecom, automotive, aerospace, manufacturing and logistics.
The other is a comparative assessment of five commercial trapped-ion companies, IonQ, Quantinuum, Oxford Ionics, Universal Quantum and Alpine Quantum Technologies, evaluated on technology differentiation, manufacturing readiness, commercial maturity, ecosystem strength, investment momentum and scalability potential, with a one-line verdict for each.
If the webinar is meant to help institutional clients understand which vendors and modalities are credible, this supplies a ready-made framework and a current set of names.
The tradeoff is relevance to the security decision.
Neither post is about cryptographic migration for digital assets: there is no discussion of exposed keys, custody, signing algorithms or a security team's timeline.
The conference post is a structured summary of other people's talks rather than original argument, while the trapped-ion post is a described infographic plus a list of companies and named individuals.
A sponsor would be paying for a landscape view they could partly assemble themselves.
Ask for audience, reach and commercial availability information before booking.
Choose Kostiantyn Polosukhin when a campaign needs post-quantum risk translated into a sector story a non-specialist will read, or wants a repeatable content format.

One post takes harvest-now, decrypt-later and follows it into travel: encrypted databases captured in breaches or intercepted in transit, held until a capable quantum computer can read them, and then used for phishing that quotes the correct flight number, date, seat and compensation figure.
That is the clearest consumer-facing illustration in the posts of why data stored today matters in five years, and the close names a tool that scans codebases, configuration files, keys and certificates for quantum-vulnerable cryptography.
The other post is a weekly five-signals format spanning industrial automation, AI, robotics, additive manufacturing and deep tech, which treats quantum hardware as a production, packaging, cooling and supply-chain problem.
If the buyer wants a recurring series rather than a one-off webinar, this shows a format that already runs.
The tradeoff is focus.
Manufacturing and industrial technology are the centre of the posts, and only part of one post addresses cryptography directly, so the travel piece is the exception rather than the pattern.
The scanning tool is the poster's own employer's product, placing the content in the same company-positioned category as Alex Pruden's references to their employer.
The loss and attack-volume figures are quoted from the post rather than independently checked.
A buyer wanting hardware modalities, qubit estimates or custody migration steps would get them from Pruden's material instead.
Ask for audience, reach and commercial availability information before booking.
This page draws on seven full LinkedIn posts by Alex Pruden, covering quantum resource estimates for breaking Bitcoin's cryptography, neutral-atom hardware, the $2.013 billion in CHIPS Act quantum awards, NVIDIA's CUDA-Q platform, the Coldcard wallet hack, AI-assisted audits of open-source Bitcoin projects, and Cloudflare's ML-DSA-44 DNSSEC test.
Comparator creators Bryant D Nielson, Alex G.
Lee, and Kostiantyn Polosukhin were reviewed for the similar-creator section, and a profile snapshot dated 8 October 2026 recorded 2,038 followers.
The posts carry no reliable publication dates, so this page describes recurring arguments rather than a chronology.
Articles and videos linked inside the posts were not read as full bodies, and no sponsorship format, rate card, audience demographics, or engagement data was available; those gaps are noted where they change a decision.
