World’s largest quantum array assembled with 6,100 qubits, 99.98 percent accuracy

Caltech physicists have created a record-breaking array of 6,100 neutral-atom qubits trapped by lasers with 99.98% manipulation accuracy. The qubits maintain superposition for 13 seconds—nearly 10 times longer than previous systems—and can be moved while preserving quantum properties. Researchers now aim to entangle these qubits, a crucial step toward building error-corrected quantum computers that could solve complex scientific problems beyond classical computing capabilities.
