论文摘要
我们提出和分析了用非选择性量子测量代替的一个热浴的两冲程量子热发动机的理论模型。我们表明，发动机的不变参考状态取决于是否通过诊断测量对周期进行监控或未监视，以确定发动机的工作输出。我们详细探讨了针对受监控和未监控情况的拟议热发动机的平均工作输出和波动。我们还确定了统一的工作中风，不变状态可以在能量基础上支持连贯性，从而导致对单一工作过程中平均能量变化的预测不同，并从标准的两项测量方法的平均工作中进行了平均工作。
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.
