Post-Quantum Cryptography (PQC)

The Qubit Report: October 21, 2026

Atomic-scale chip screening falls from three hours to one and cat-qubit demonstrators complete core error-correction blocks on real 6- and 12-qubit chips. A CUDA-Q decoder records 12 percent fewer logical errors on Google hardware data while university teams gain unlimited access to Canada’s IBM Quantum System One. Networks begin formal interoperability talks and sovereign hybrid stacks absorb quantum circuits as ordinary workloads. Click through for every measured gain and partnership that landed today.

The Qubit Report: October 20, 2026

The Qubit Report for October 20, 2026 opens with VTT and Q-STAR formalizing a Japan-Finland quantum collaboration. Oxford researchers then held mixed-species atomic entanglement for more than 10 seconds while CityUHK found a quantum route to entropy-free energy transfer. Defence investments, a mobile-app PQC survey and regional bets in Palm Beach round out the day, giving readers concrete next steps to explore.

Australia’s stage-two quantum grants total $12.3 million, not the $123 million sitting in the URL slug, the same day Xanadu and GlobalFoundries called a manufacturing partnership. Forescout says only 31 percent of exposed hospital systems support TLS 1.3, and SEALSQ’s $10 million WISeSat PIPE is a related-party deal. The gene-search ‘16.8x’ is a GPU simulator result, and the excerpt stops before the method.

WISeQey began trading as WQEY on Nasdaq and SIX the same Monday SAIC bought Information Security Corporation for undisclosed terms. The deals sit next to a Quantinuum cloud memo in Perth and a D-Wave supply-chain fund at the University of Arkansas, neither of which installs a machine. The $15 billion figure in the Nu Quantum interview is McKinsey’s 2035 communications market, and the interview has the split.
