“…Starting from the seminal contribution of [9], this field has quickly grown as an active area of research. A non-exhaustive list of previous work includes studies examining quantum Otto cycles with one of the thermal baths by a non-selective measurement of different kinds of working fuel (WF) quantum systems [11][12][13][14][15], engines entirely fuelled by quantum measurements [16], using quantum measurement to fuel two-stroke absorption refrigerators [17], entangled twoqubit heat engines operated by measurement and feedback [18], and work extraction from thermal states by phase sensitive homodyne measurements [19].…”

We propose and analyze the theoretical model for a two-stroke quantum heat engine with one of the heat baths replaced by a non-selective quantum measurement. We show that the engine's invariant reference state depends on whether the cycle is monitored or unmonitored via diagnostic measurements to determine the engine's work output. We explore in detail the average work output and fluctuations of the proposed heat engine for the monitored and unmonitored cases. We also identify unitary work strokes for which the invariant states can support coherences in the energy basis leading to differing predictions for the average energy change during the unitary work strokes and the average work from the standard two-projective measurement approach.
