5 articles covering "neutral atoms"
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.
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.
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.
