Two-level system hyperpolarization with a quantum Szilard engine

By implementing a quantum Szilard engine, we show that a superconducting granular aluminum fluxonium qubit is coupled weakly to a two-level system (TLS) environment of unknown physical origin. Since the TLSs are much longer lived than the qubit, non-exponential relaxation and non-Poissonian quantum jumps can be observed. These dynamics can be modeled using the stochastic Schrödinger equation and the Solomon equations.
