Memory coherence of a sympathetically cooled trapped-ion qubit
We demonstrate sympathetic cooling of a C 43 a+ trapped-ion "memory" qubit by a C 40 a+ "coolant" ion sufficiently near the ground state of motion for fault-tolerant quantum logic, while maintaining coherence of the qubit. This is an essential ingredient in trapped-ion quantum co...
