Achieving 99. 76% accuracy on a quantum operation whilst operating at lower energy levels was previously considered mutually exclusive. Now, physicists have demonstrated this high-fidelity two-qubit gate in an array of cooled caesium atoms, matching leading room temperature performance with significantly reduced potential for errors caused by atomic instability.
