  Over the past several decades, a rich series of experiments has repeatedly
verified the quantum nature of superconducting devices, leading some of these
systems to be regarded as artificial atoms. In addition to their application in
quantum information processing, these `atoms' provide a test bed for studying
quantum mechanics in macroscopic limits. Regarding the last point, we present
here a feasible protocol for directly testing time reversal symmetry through
the verification of the microreversibility principle in a superconducting
artificial atom. Time reversal symmetry is a fundamental property of quantum
mechanics and is expected to hold if the dynamics of the artificial atom
strictly follow the Schr\"odinger equation. However, this property has yet to
be tested in any macroscopic quantum system. In the end, as an application of
this work, we outline how the successful implementation of the protocol would
provide the first verification of the quantum work fluctuation theorems with
superconducting systems.
