Story summary

California Institute of Technology (Caltech) researchers report a record 6,100 stable qubits created by laser-trapping cesium atoms, surpassing the 1,180-qubit benchmark.
Qubits maintained superposition for 13 seconds, nearly ten times longer than earlier systems.
The team demonstrated 99.98% precision in manipulating atoms, advancing quantum physics.
Future work aims to entangle qubits, but experts caution more experiments are needed.
