IBM and UChicago ran a 70-logical-qubit circuit beyond classical simulation reach and verified it to 95% confidence, one of three quantum-advantage papers released the same day with mixed outside reception.

Honeywell Technologies' first quarterly report as a standalone automation company beat prior guidance and included a $6.6 billion one-time gain from deconsolidating Quantinuum after its IPO.

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.

Physicists built a photonic quantum heat engine that uses indefinite causal order to generate work and refrigeration simultaneously, reversing the everyday direction of heat flow.

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.

Using a single trapped strontium-88 ion, an Oxford group built cat states whose components are themselves squeezed and trisqueezed states, reporting Wigner negativity and greater quantum resourcefulness than standard cat or Fock states.

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.

Dutch quantum chip firm QuantWare closes a record $178M Series B to scale its VIO processor platform and open KiloFab, the world's largest dedicated quantum foundry.

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.
