Caltech Builds World’s Largest Neutral-Atom Quantum Computer

Caltech has advanced quantum computing by creating the largest neutral-atom quantum system to date, trapping 6,100 cesium atoms as qubits in a single array. This achievement involves maintaining coherence for approximately 13 seconds with an impressive operational accuracy of 99.98%. The ability to operate on such a large scale is a significant improvement over previous experiments, which contained only hundreds of qubits. The team utilized highly focused laser technology to move individual atoms within the array while preserving their delicate quantum state. This flexibility allows for more dynamic error correction possibilities in future systems. As global competition increases in quantum computing development, this milestone highlights the potential of neutral-atom systems amidst emerging technologies. The Caltech team's focus is on linking qubits through entanglement—a critical step for executing large-scale quantum computations and devising practical applications across various fields including chemistry and materials science.
