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.

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.

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…

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.

Dutch Quantum Strategy Says Prepare for Q-Day Around 2030. Medium-Risk Systems Have Until 2035.
Dutch central-government organizations are asked to move high-risk systems to post-quantum cryptography by the end of 2030 under a new national strategy, which expects a CRQC between 2029 and 2035 and adds no money for the migration.

Crypto-Agility for Digital Assets: Chains Are Planning One Post-Quantum Change When They Will Need Several
Zcash replaced a flawed proof circuit and sealed a pool then worth $1.7 billion within 60 days. Bitcoin and Ethereum are planning one post-quantum change. Crypto-agility means a chain can change its cryptography again, and retire what it replaced.

Crypto-Agility Is the Goal. The PQC Migration Is Only Its First Test.
Post-quantum algorithm choices are already changing: a NIST candidate was withdrawn the day after an attack went public, and BSI advised against Classic McEliece in new developments. Build a crypto-agility program and make the PQC migration its first test.
