AB - Measurement-based cooling is a method by which a quantum system, initially in a thermal state, can beprepared probabilistically in its ground state through some sort of measurement. This is done by making ameasurement that heralds the system being in the desired state. Here we demonstrate the application of ameasurement-based cooling technique to a trapped atomic ion. The ion is precooled by Doppler laser coolingto a thermal state with a mean excitation of ¯n ≈ 18 and the measurement-based cooling technique selects thoseoccasions when the ion happens to be in the motional ground state. The fidelity of the heralding process is greaterthan 95%. This technique could be applied to other systems that are not as amenable to laser cooling as trappedions.
