The day in brief

Intel announced a definitive agreement on October 26, 2026, to acquire quantum software company Classiq ¹. The proposed combination brings Classiq’s quantum algorithm synthesis platform together with Intel’s silicon spin-qubit work, with closing expected in the first half of 2027 ¹. NIH opened registration for QuSAFE, a $7.1 million challenge seeking quantum-enabled sensing prototypes for preclinical safety testing ².

CoDecoder cut decoding time by as much as 124-fold in a benchmark on a bivariate-bicycle code ³. The hybrid system also reduced decoding failures in registered tests, which used memory experiments and GPU-based timing rather than a live quantum processor ³. OQTOPUS’s method reserves idle physical qubits between circuits to address crosstalk when multiple users run circuits on one chip ⁴.

OptQC researchers simulated logical Bell-resource error bounds below 10⁻⁵ under two specified noise conditions ⁵. Telefónica and IQM plan to install an IQM Spark at Universidad Politécnica de Madrid before the end of 2026 ¹⁰. IDEMIA Secure Transactions and KT are implementing post-quantum algorithms on a SIM-equipped smart-card platform for South Korea’s 2026 pilot ⁸.

The five

• Intel Agrees to Acquire Classiq for Full-Stack Quantum Computing

  Intel announced a definitive agreement on October 26, 2026, to acquire quantum software company Classiq. The planned combination pairs Classiq’s quantum algorithm synthesis platform with Intel’s silicon spin-qubit work, with closing expected in the first half of 2027.

• NIH Opens Registration for $7.1 Million QuSAFE Challenge

  NIH opened registration on October 25 for QuSAFE, a $7.1 million competition to develop quantum-enabled sensing prototypes for preclinical safety testing. The challenge seeks measurements in human-cell laboratory models that could improve detection of biological signals relevant to drug toxicity and safety.

• CoDecoder Cuts Quantum Decoding Time by Up to 124×

  Researchers report that CoDecoder, a neural front end for existing quantum error-correction decoders, reached a 124-fold speed-up in a benchmark on a bivariate-bicycle code. In registered tests, the hybrid approach also reduced decoding failures, but its results come from memory experiments and GPU-based timing rather than a live quantum processor.

• OQTOPUS Adds Buffer-Qubit Reservations Against Crosstalk

  A paper describes adding buffer-qubit reservations to OQTOPUS, a software stack for running quantum circuits from multiple users on one chip. In a test on one superconducting quantum computer, observable dephasing changes appeared only at qubits adjacent to the attacker circuit; the authors also tested the allocator’s buffer reservations.

• OptQC Simulates Sub-10⁻⁵ Errors for Optical Bell Resources

  An OptQC team reports simulated logical Bell-resource error bounds below 10⁻⁵ in a modular optical quantum-computing design. The result depends on a specified noise model and does not certify the processor’s full set of logical gates.
