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.

Supervisors Can Measure a Sector’s Cryptographic Exposure Without Collecting Anyone’s Inventory
Under the EU's Cyber Resilience Act, authorities may collect software inventories before anonymizing them. Supervisors measuring cryptographic exposure can skip that step, with federated queries, secure aggregation and private set intersection run against each firm's own CBOM.

Google Ran Magic State Cultivation on Willow and Cut Magic-State Error 40-Fold. The Test Covered Only the Protocol’s Smallest Version.
Google put an upper bound of one to two in 10,000 on the error of T states cultivated on Willow. The result supports one assumption in Google's sub-million-qubit RSA-2048 estimate and leaves the rest of a factory untested.

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.

PQC for MSSPs and Consultancies: Opportunity and Risk
Post-quantum migration will keep security consultancies and MSSPs busy for a decade, but the revenue is in PKI, legacy systems, vendors and governance, not in scans. Clients will also check each provider's own cryptography before they buy.

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.
