What’s Happening in Quantum — and What It Means
IBM’s AI Agents Cut a Quantum Decoder’s Estimated Latency 52-Fold for $26 and 204-Fold for $299
IBM let AI coding agents rework the hardware design of its Relay-BP quantum decoder, at an estimated $26 in inference with open-weight models. By the synthesis tool's estimates, even the best design is far slower than IBM's hand-written decoder ...
MITRE Rated Eight Enterprise Technologies on Post-Quantum Readiness. Key Exchange Is in General Release in Five, Signatures in Two.
In a July review of public evidence, MITRE found no enterprise technology category with FIPS-validated post-quantum support and no post-quantum hardware TPM on sale. What that means for agencies planning toward 2030 and 2031 ...
Starknet Asks Its Stakers Whether to Research Leaving Ethereum Over Quantum Risk
StarkWare says Starknet could finish its post-quantum migration on its own schedule if it left Ethereum. A forum commenter named the cost. One of Starknet's most direct quantum exposures, its users' elliptic-curve keys, does not depend on Ethereum ...
Europe’s Quantum Industry Association Asks the EU for Faster Export Licensing
The European Quantum Industry Consortium wants electronic licensing in every member state, published processing times and South Korea added to EU001. Its members report lost customers, but QuIC gave no figures on licensing times ...
Coinbase, Which Says It Holds About 12% of All Bitcoin, Sets Out What It Needs From Bitcoin’s Post-Quantum Signatures. Its Request for Multi-Party Signing Is the Hardest to Meet.
On October 13, Coinbase listed what its custody systems need from Bitcoin's post-quantum signatures: multi-party signing, HSM support and a stateless signing mode. The SHRINCS draft already includes the stateless mode. Post-quantum multi-party signing is still a research topic ...
Germany Sets a 2030 Post-Quantum Target for High-Risk Systems in Government, Business and Critical Infrastructure
BMI, BMDS and BSI have turned the EU's post-quantum roadmap into German guidance. Before 2030 comes an end-2026 checkpoint: named owners, a first cryptographic inventory, and a link to the state-of-the-art duty in the BSI Act ...
Singapore Will Pay Up to 70% of Quantum-Safe Migration Pilots, Critical Infrastructure First
Singapore's cyber regulator will now pay up to 70% of the cost of quantum-safe migration pilots, with priority for the critical infrastructure owners it told to finish by 2031. The pilot reports could show how much effort migration takes ...
Michael Saylor’s Quantum Claims About Bitcoin, Checked
Strategy's executive chairman says Bitcoin should wait for a quantum threat before upgrading. Its upgrade record, its draft proposals, the arithmetic of block space and his company's own SEC filings all say otherwise ...
A Key Step of a Quantum Attack on Bitcoin and Ethereum Now Fits in Under 900 Logical Qubits Within Google’s Gate Budget
An open leaderboard now lists secp256k1 point-addition circuits under 900 logical qubits that stay within Google's published Toffoli bound. Whether that saves a quarter of the physical qubits depends on the machine. Nobody has compiled a full attack with them ...
IonQ Is Buying Elisity for Access to CISOs. Most of the Post-Quantum Capabilities Those CISOs Need First Are Still Missing.
IonQ's hardware acquisitions shorten its own path to better quantum computers. Its security purchases face a different test: whether a CISO planning a post-quantum migration can get inventory, signature migration and validated cryptography from IonQ ...
The US Energy Department Named Eight Science Problems for Its First Fault-Tolerant Quantum Computers Without Setting Problem Sizes or Classical Baselines
The US Energy Department aimed its eight Quantum Genesis priority applications at the right science for fault-tolerant quantum computers but published no problem sizes or classical baselines. I compare them with resource estimates for related problems ...
IBM and Rutgers Controlled Quantum Chaos on 100 Qubits With Thousands of Mid-Circuit Resets. The Experiment Was Not Quantum Error Correction.
In a Nature Physics paper, IBM and Rutgers researchers drove 100 superconducting qubits from chaotic to controlled dynamics with mid-circuit resets. The physics is sound. The error-correction framing in the Rutgers announcement goes beyond anything the experiment tested ...
IonQ Entangles a Trapped Ion With a Diamond Memory 1,000 Times a Second at 88% Fidelity. Its Own Paper Puts the Rate Needed Between Modules 10 to 100 Times Higher.
IonQ's preprint entangles a barium ion with a silicon-vacancy memory in diamond at four times the rate of the fastest photonic link between two trapped ions. I compare it with what error-corrected modules need and with IonQ's press release ...
Pentagon’s $350 Million Quantum Package Backs DARPA Testing and PsiQuantum Manufacturing
The Pentagon’s $350 million quantum package combines DARPA verification funding with conditional manufacturing finance for PsiQuantum. A parallel applications effort will bring quantum researchers and defense users together to define what future machines should actually do ...
DARPA Advances Four More Quantum Companies to Stage C
Six quantum companies have reached DARPA’s final evaluation stage. As Atom Computing, Diraq, IBM and IonQ join Microsoft and PsiQuantum, we examine the funding, hardware evidence and what Stage C selection means for the prospect of economically useful quantum computing by 2033 ...
Europol Urges Early Action on Quantum Threats to Crypto Wallets and Stored Data
Europol's October 2026 reports place quantum risk on wallet signing keys and long-lived data. Since they were drafted, the IETF has published post-quantum OpenPGP and the hybrid TLS standards behind key exchange already running in major software ...
US Agencies Had Until May 2023 to Inventory Quantum-Vulnerable Cryptography. Auditors Found One of 24 Inventories Complete.
Washington called the federal inventory of quantum-vulnerable cryptography comprehensive in 2023. An audit made public on October 6 checked the inventories against agencies' own records and asked sampled agencies for evidence. One passed, and most sampled entries had no documentation ...
Modular Quantum Error Correction: 10x in Simulation
Google Quantum AI and DeepMind simulated a modular error-correction memory that needs a tenth of the surface code's physical qubits per logical qubit. The abstract's 30× figure comes from codes too large to simulate ...
