Quantum Computing

HRL published a Nature paper on an 18-qubit silicon spin processor run by an onboard cryogenic chip, days after IBM agreed to acquire the lab.

Quantinuum, Caltech, UChicago, and Harvard used 54 qubits on the H2 processor to build a universal gate set from non-Abelian anyons, aiming to sidestep costly magic state distillation.

Zhongqi Wuliang showed Qinghe No. 1, a neutral-atom quantum computer built to fit a standard data-center rack, at WAIC 2026 in Shanghai.

The neutral-atom startup landed a $300 million Series A co-led by ARCH, Spark, and Khosla, months after launching with Caltech research claiming far fewer qubits are needed for useful quantum computing.

The company reports the first full toric-code error-correction demonstration on neutral atoms, sustaining logical memory across up to 90 cycles by reloading lost qubits from a reservoir.

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.
