Your TLS connection succeeds. But is it post-quantum protected? Java 27 can fall back from hybrid key exchange to classical X25519. Babneet Singh explains how to detect the difference and verify your handshake: https://javapro.io/2026/11/10/java-27s-post-quantum-tls-handshake-how-jep-527-brings-hybrid-key-exchange-to-jsse/

Pentagon Faces 5-Year Deadline to Fortify Systems Against Quantum Computer Attacks
The Pentagon has just 5 years to shield its systems from the looming threat of quantum computer attacks, a challenge made more urgent by the uncertainty of adversaries' current capabilities. With the White House's Executive Order 14412 setting firm deadlines, the clock is ticking for defense…

(One of) the year's biggest papers on what it takes to break RSA and ECC goes public tomorrow. I have read it. It is serious work, but it is also going to be badly misread. It changes what a codebreaking quantum computer could look like, if one big assumption holds. Expect this paper to dominate the conversation for days, including various sky-is-falling takes.
Luckily, our Q-Day estimates webinar was already on the calendar for tomorrow. The paper goes public one hour before we go live. This year Iceberg Quantum, Google, Oratomic and IonQ each published careful resource estimates, and each time the headlines exaggerated. Expect the same tomorrow.
We will put tomorrow's paper next to previous ones and go through:
- what it actually achieved in this paper and throughout the year (and with what assumptions)
- whether any of it moves Q-Day
- what to tell your board when it asks, because they will
Free one-hour webinar from Quantum Academy and Applied Quantum, tomorrow, 29 October, at 15:00 UTC (16:00 CET, 11:00 ET). It will be one of the first independent readings of the paper.

Gang of 9 looks to tackle common standards to protect blockchains against future quantum powered attacks.
The work will be divided into four groups:
1) blockchain migration
2) post-quantum zero-knowledge systems
3) wallet security
4) cross-network compatibilityParticipants include: Quantus, American Fortress, Intmax, Keystone, Midnight Foundation, Postquant Labs, Abelian, The Vault, and Hacken. https://www.cointribune.com/en/quantum-alliance-targets-bitcoins-future-security/

Microsoft’s readiness guidance asks organizations to test certificate systems before wider adoption of quantum-resistant methods.
The transition may affect applications, devices, certificate chains and operational processes; Microsoft says organizations often lack a complete view of their certificate dependencies.
Its TLS pilot, launched on 27 August 2026, lets approved certificate authorities test cer…

There seems to be a remarkably strong correlation on LinkedIn between people warning about the PQC threat and job titles containing “Account Manager” or “Sales”.
I’m sure it’s purely coincidental.

Medical Devices Lag in Quantum-Secure Upgrade Push
The devices healthcare organizations rely on most to deliver patient care are also the ones lagging behind in quantum-secure upgrades, making it crucial to get visibility into these assets and the data they handle to build a practical migration strategy. A recent investigation found that only 6% of Internet of Medical…

I have a problem with the term Post Quantum Cryptography (PQC) it implies a natural and simple progression from classical crypto to quantum crypto - it also creates the impression that we can prove a cryptography is unbreakable which isn't how that works
Quantum Resistant is better as it conveys that special attention is made to thwart quantum attack vectors without implying an objective standard of security
