What’s Happening in Quantum — and What It Means
Quantum Academy Launches 68 PQC and Quantum Courses, With Proctored Certification Exams
Quantum Academy's next live online sessions start October 19, priced from US$379 to US$8,499 for the six-week Certified Chief Quantum Officer program. Disclosure: I founded it, and some of its instructors work at my consulting firm ...
NSA Rewrites Its QKD Guidance: Same Verdict, a New Certification Argument
Almost six years after its first QKD statement, NSA has revised it. National security systems still get a no, and NSA now says certified security can erode. I agree, and argue the US should fund a limited operational QKD program ...
Germany’s BSI Advises Against New Classic McEliece Deployments After Researchers Estimate Key Recovery Below Its Claimed Security Levels
Less than two months after a new Classic McEliece distinguisher appeared, three research groups estimate key recovery below every claimed security level, and Germany's federal cybersecurity agency wants no new projects built on it. No practical attack exists yet ...
NATO’s First Quantum Roadmap: Sea Trials, a PQC Pilot and No Public Date for Its Own PQC Migration
Allies approved NATO's first quantum technology roadmap in July. Its public summary dates sensor trials, standards work and a cryptography pilot. A separate procurement notice estimates the pilot at €8 million and adds a before-2030 goal ...
QuTech Builds Leakage Removal Into Qubit Readout, and Its Clearest Gain Is in Stability Experiments
QuTech's leakage reduction unit works inside a qubit measurement and adds no time to two-level readout. At baseline leakage it left memory-experiment error rates unchanged but raised a stability experiment's error-suppression factor by 29%, or 54% with three-level readout ...
In a Survey of 160 Quantum Firms, 90% Buy From Abroad and About a Quarter Buy From China
Six industry associations asked 160 quantum companies where their suppliers, customers and factories are. I separate foreign from home answers in the country counts, then look at China, the competing lists of like-minded countries and what the survey left out ...
Infleqtion Hits 30 Logical Qubits With Error Detection. Its Original 2026 Target Called for Error Correction.
Infleqtion met its 2026 goal of 30 logical qubits on Sqale with eight-atom blocks that detect errors and discard failed runs. The goal it replaced in 2025 called for error correction ...
Microsoft and Qolab Propose Four Conditions for a Scalable Logical Qubit. DOE’s $215 Million Competition Leaves Its Test to Negotiation.
Troyer, Nayak and Martinis want the word scalable reserved for logical qubits kept alive by repeated error correction and real-time decoding. I checked ten studies and announcements since April 2024 against their conditions and DOE's new competition rules ...
IonQ Shows a Single Laptop CPU Can Decode a Simulated 408-Logical-Qubit Trapped-Ion Computer in Real Time
IonQ researchers decoded simulated trapped-ion workloads on 12 Apple M4 Max cores, the largest with 408 logical qubits and another with over a million T gates, adding under 0.3% delay at a two-qubit error rate of one in 10,000 ...
China’s Next-Generation Crypto Candidates Drew 104 Public Findings in Three Days. Researchers Broke Five Designs on Day Two
Within three days of China publishing its first-round candidates, public reports listed 104 findings against 65 of them. Saarinen's AI-assisted sweep found code bugs; researchers posting to ICCS's own forums found the design breaks ...
FIPS 140-2 Goes Historical Today – What Actually Changes and What Doesn’t
Every remaining FIPS 140-2 certificate moves to the CMVP Historical list on September 21, 2026. The sunset changes procurement, not operations – but the supply-side gap in FIPS 140-3 validated modules makes the transition harder than the seven-year runway implied ...
Apple Joins the Merkle Tree Certificate Consensus – and Raises the Bar
Apple's Root Program has committed to Merkle Tree Certificates for TLS with requirements that go beyond Chrome's in key respects, while taking the composite-algorithm path for S/MIME – confirming the two-track PKI fork organizations must plan for ...
RSA-896 Factored With Claude on Spare GPUs, 16 Days After RSA-260
Stephen Weis of Anthropic used Claude to port CADO-NFS to GPUs and factored RSA-896 on idle capacity, 16 days after Cognition's RSA-260 record. RSA-2048 remains about 35 billion times harder and needs a quantum computer ...
Physicists in Guangzhou Confirm Feynman’s Path-Integral Rules With Single Photons, but Not That They Take Every Path
South China Normal University physicists measured single-photon propagators at 98.5% fidelity and multiplied them into 1.4 million path amplitudes. Quantum mechanics, its rival interpretations and classical wave optics predict the same propagators ...
Europe’s Chips Act 2.0 Keeps Quantum Pilot Lines but Leaves Quantum Fabrication Out of Its Strategic-Project Priorities
The European Quantum Industry Consortium says the Chips Act 2.0 proposal names quantum foundries without an instrument to build one. I checked its reading of the annexes and set it against what the US government funded in September ...
Stuttgart Physicists Measure an 11.5-Millisecond Lifetime for Circular Rydberg Atoms at Room Temperature. The Group’s Best Circular-Qubit Coherence Time Is Still 278 Microseconds.
A Stuttgart group used two coated glass plates to keep trapped strontium atoms in circular Rydberg states for over 10 ms without a cryostat. I check the three claimed records and what neutral-atom qubits still need ...
Every Headline RSA-2048 Estimate Assumes Qubits That Work. A Sydney Team Measured What Happens When They Don’t.
On a single IBM chip, a distance-5 surface code lost to a distance-3 even after the defective components were routed around. The headline estimates of what breaking RSA-2048 takes assume they all work ...
DOE’s $215 Million Q Competition Puts a Price Tag on Fault-Tolerant Quantum Computing – and a Deadline
The DOE's Quantum Genesis Q Competition offers up to $215 million for fault-tolerant quantum computers with at least 100 logical qubits – not physical qubits – by September 2028, paid through milestone payments and equal-split incentive pools ...
