DARPA's Heterogeneous Architectures for Quantum program will fund 19 teams over 24 months to combine different qubit types into unified quantum systems, abandoning the single-technology approach.
Nvidia's new Ising family targets quantum error correction and calibration, claiming 2.5x faster and 3x more accurate decoding than the current open-source standard, with more than 20 labs and hardware makers already on board.
Rigetti Computing has made its 108-qubit Cepheus-1-108Q system generally available through its own cloud platform and Amazon Braket, marking the first gate-based quantum processor exceeding 100 qubits on AWS.
A European team eliminates mid-circuit measurements from fault-tolerant quantum computing, running Grover's algorithm on three logical qubits encoded in eight trapped ions without pausing to read error syndromes.
A Caltech-backed startup claims utility-scale quantum computers need far fewer qubits than previously estimated, potentially accelerating the timeline for cryptographically relevant machines to the end of the decade.
2026 marks the transition from noisy quantum experiments to error-corrected commercial systems, with neutral atom platforms from QuEra, Atom Computing, and Pasqal leading the charge.
D-Wave Quantum Inc. announces $550 million acquisition of Quantum Circuits Inc. to combine annealing and gate-model quantum technologies, with first dual-rail system planned for 2026 delivery.
