Implication

Experimental scheme verifies quantum nonequilibrium fluctuation relations using single-qubit interferometry, indicating broader application in quantum systems.

Key Points

The aim is to verify quantum nonequilibrium fluctuation relations using single-qubit interferometry.
Utilized Ramsey interferometry with a single probe qubit.
Focused on a time-dependent quench of the motional state of a trapped ion.
Demonstrated the method utilizing the internal pseudospin as the probe qubit.
Successfully extracted the characteristic function of the work distribution for a nonequilibrium quench.
Provided a framework for characterizing nonequilibrium processes in various quantum systems.
Indicated applicability to both single particles and many-body atomic systems.
