- Abstract: Quantum thermodynamics is aimed at grasping thermodynamic laws as they apply
to thermal machines operating in the deep quantum regime, a regime in which
coherences and entanglement are expected to matter. Despite substantial
progress, however, it has remained difficult to develop thermal machines in
which such quantum effects are observed to be of pivotal importance. In this
work, we report an experimental measurement of the genuine quantum correction
to the classical work fluctuation-dissipation relation (FDR). We employ a
single trapped ion qubit, realizing thermalization and coherent drive via laser
pulses, to implement a quantum coherent work protocol. The results from a
sequence of two-time work measurements display agreement with the recently
proven quantum work FDR, violating the classical FDR by more than $10.9$
standard deviations. We furthermore determine that our results are incompatible
with any SPAM error-induced correction to the FDR by more than 10 standard
deviations. Finally, we show that the quantum correction vanishes in the
high-temperature limit, again in agreement with theoretical predictions.
