Weak measurement driven thermal machines based on coupled qubits

ORAL

Abstract

We study the role of weak measurement and feedback in determining the power and performance of coupled qubit-based thermal machines. We investigate the system where the qubits are connected to a detachable bath, and one is free to specify the type of measurement and feedback performed on them. We consider the effect of both discrete and continuous measurements of the system. We examine the power output when compared to a single qubit setup, and the effect of coupling and measurement strength on the performance of the machine. Finally, we specify the type of feedback for which an optimal operational condition is achieved.
