Caltech physicists have created the largest neutral-atom quantum computer to date, trapping 6,100 cesium atoms as qubits in a single array. The result, published in Nature on Thursday, represents a significant increase over previous arrays, which contained only hundreds of qubits. Researchers scaled their system from the hundreds of qubits typical in past experiments to more than 6,000, while maintaining stability and precision at levels needed for practical machines. The team said it achieved coherence times of about 13 seconds—nearly 10 times longer than past experiments—while performing single-qubit operations with 99.98% accuracy.
