Quantum Computing

Google Quantum AI and Google.org are funding five universities to develop quantum sensors and algorithms for molecular biology, targeting drug discovery and human health.

ETH Zurich researchers published a Nature paper demonstrating noise-resistant geometric-phase swap gates for neutral-atom qubits, achieving 99.91% fidelity simultaneously across 17,000 qubit pairs in under a millisecond.

Researchers led by Leibniz Hannover, Stuttgart, and Nanjing have published the first time-bin QKD link driven by an on-demand telecom quantum dot, holding stable across 120 km of standard fiber for six hours straight.

A 120-qubit simulation finished in two minutes versus more than 100 hours classically, with the team also reporting direct observation of spin-charge separation on 62 qubits.

London-based Quantum Motion has raised $160 million in Series C funding co-led by DCVC and Kembara to commercialize silicon-CMOS quantum processors that the company says fit in three standard server racks.

Researchers from the Wellcome Sanger Institute and University of Oxford encoded the Hepatitis D virus genome onto IBM's 156-qubit Heron processor, marking the first time a complete genome has been processed on quantum hardware.

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.

Paris-based C12 published a four-stage plan to scale its carbon nanotube spin-qubit processors from 16 physical qubits in 2027 to over 100,000 by 2033, betting a solid-state modality can catch incumbents on error-corrected quantum computing.

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.

India's National Quantum Mission has demonstrated a 1,000-kilometer quantum-secured communication network using QNu Labs' indigenous ARMOS QKD platform, reaching the halfway mark of its 2,000 km target in under two years — well ahead of the original eight-year timeline.

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.

Quantum Computing Inc. installed its Dirac-3 quantum optimization machine on the Quantum Corridor network connecting Chicago and Hammond, Indiana, marking the first time a quantum computer has been deployed on a QKD-secured commercial fiber network spanning U.S. state lines.
