Neutral-atom quantum computer reaches new milestone
Using optical tweezers, researchers at Caltech achieved 99.98% accuracy in single-qubit operations while maintaining coherence for 13 seconds in a groundbreaking neutral-atom quantum array.
Caltech physicists have developed a groundbreaking neutral-atom quantum computer, trapping 6,100 caesium atoms as qubits in a single array. Published in Nature, the achievement marks the largest such system to date, surpassing previous arrays limited to hundreds of qubits.
The system maintains exceptional stability, with qubits coherent for 13 seconds and single-qubit operations achieving 99.98% accuracy. Using optical tweezers, researchers move atoms with precision while maintaining their superposition state, essential for reliable quantum computing.
The milestone highlights neutral-atom systems as strong contenders in quantum computing, offering dynamic reconfigurability compared to rigid hardware. The ability to rearrange qubits during computations paves the way for advanced error correction in future systems.
As global efforts intensify to scale quantum machines, Caltech’s work sets a new benchmark. The team aims to advance entanglement for full-scale computations, bringing practical quantum solutions closer for fields like chemistry and materials science.
