What’s Happening in Quantum — and What It Means
Mitten Codes Put 195 Logical Qubits in 975 Physical Qubits, Complete with Fault-Tolerant Processor Design
Caltech and Oratomic introduce mitten codes, a family of 20%-rate qLDPC processor codes. In simulations, a [[540, 108, 18]] block produced two failures across 15 billion surgery quops at 0.1% physical error rate, consistent with an expected processing capacity of order 10 billion quops ...
HKMA Gives Hong Kong Banks a 2.3 Out of 10 on Quantum Readiness, Targets Full Migration by 2030
HKMA's first Quantum Preparedness Index scores Hong Kong's banking sector PQC readiness at 2.3 out of 10. Most respondents remain at an early stage, while the regulator targets full sectoral readiness by 2030 ...
87% of Organizations Are Pursuing PQC. Only 7% Have Deployed It.
DigiCert's second annual PQC survey finds at-scale certificate deployment barely moved in a year. The barrier profile now points to execution, not awareness, and that tells us more than the headline number ...
HRL Built a Silicon Quantum Processor That Controls Itself Inside the Cryostat. IBM Agreed to Buy the Lab.
HRL Laboratories put a quantum processor, its controller, and a superconducting cable inside a single cryostat. The system ran error correction by itself. Eight days later, IBM announced it was buying HRL ...
MAS Targets Quantum Resilience for FIs by End of Decade
Singapore's central bank will issue supervisory expectations with progressive milestones for financial institutions' quantum-safe migration. The stated aim: quantum resilience before the end of this decade ...
Economist Quantum Article: Best in Media, Still Wrong
The Economist's July 2026 quantum primer is the best mainstream coverage I've seen. I still found errors on how quantum computing works, what Shor's algorithm threatens, and which data sources deserve trust. If even The Economist gets this wrong, everyone should check their sources ...
IBM Declares a “Quantum Advantage Era.” The Three Papers Make Different Claims.
IBM coordinated three quantum advantage announcements. The validation advances are real, but the papers make materially different claims ...
Neutral-Atom Roadmap Charts a Path to Quantum Utility
A multi-institutional roadmap for neutral-atom quantum computing puts cryptanalysis on its convergence chart. Here is what the data and the assumptions actually show ...
EY Installed a Quantum Computer in Toronto. Nobody Will Say What It Is.
The regulation behind Europe's €30 billion AI Gigafactories also rewired the EU's quantum strategy. The institutional convergence has consequences that the AI headlines buried ...
Europe’s Biggest AI Sovereignty Bet Had a Quantum Strategy Buried Inside It
The regulation behind Europe's €30 billion AI Gigafactories also rewired the EU's quantum strategy. The institutional convergence has consequences that the AI headlines buried ...
Pure ML-KEM for TLS 1.3 Reaches IETF Last Call
The IESG is taking final comments on standalone ML-KEM key establishment for TLS 1.3 until August 13, after three Working Group Last Calls, a contested consensus determination, and a chairs' refusal to release the numbers behind it ...
AI Broke a NIST Candidate. Not Your Encryption
Claude Mythos Preview recovered HAWK-256 challenge keys and improved a 13-year-old reduced-round AES result. ML-KEM, ML-DSA, SLH-DSA, Falcon, and production AES are untouched. The real shift is the cost of finding flaws ...
Bitcoin’s Institutions Take On the Quantum Security Bill
Nine institutions pledged $15 million over three years for Bitcoin security, with quantum readiness the first workstream. Galaxy separately announced up to $5 million in developer grants for post-quantum work ...
PsiQuantum’s $125 Million DARPA Deal Buys Verification
DARPA signed a $125 million agreement to verify PsiQuantum's utility-scale photonic designs in QBI's final stage, where Microsoft remains the only other performer under evaluation ...
SAXON Q’s 128-Qubit Diamond Quantum Computer: Real Fabrication Advance, Misleading Qubit Count
SAXON Q opened orders for a 128-qubit room-temperature diamond quantum computer. The disclosed architecture uses sixteen separate eight-qubit cores with no published inter-core entanglement. The peer-reviewed fabrication advance is real ...
ECC Attack Circuit Drops to 835 Logical Qubits
The same Tsinghua-Peking group whose April preprint reached 1,333 qubits for a 256-bit ECC attack has pushed to 835, the lowest yet. The circuit is narrower, but the gate count is 20 times higher than the leading alternative. Smaller machine, longer run ...
China’s Neutral-Atom Sprint: Three Generations in Nine Months — But Where Are the Benchmarks?
China's CAS-linked neutral-atom ecosystem unveiled three quantum computer systems in nine months, each in a smaller package than the last. The iteration speed on form factor has no Western counterpart. Not one system has published peer-reviewed performance data ...
A Universal Topological Gate Set Runs on Today’s Hardware
Researchers braided and fused non-Abelian anyons on Quantinuum's trapped-ion hardware to build the first universal topological gate set, a proof of principle for fault-tolerant computing's other path ...
