英文摘要: The thermodynamic influence of quantum probing on an object is studied. Here, quantum probing is understood to be a pre-measurement based on a non-demolition interaction, which records some information of the probed object but does not change its energy state when both the probing apparatus and the probed object are isolated from the environment. It is argued that when the probing apparatus and the probed object are immersed in the same equilibrium environment, the probing can affect the effective temperature of the object or induce a quantum isothermal process for the object to transfer its energy. This thermodynamic feature can be regarded as a witness of quantum probing.
