Quantum thermal management devices based on strong coupling qubits

摘要

We study the performance of a thermal management device with small scales by considering a strong coupling between quantum qubits.A small change of the thermal current at the base will cause a great change to the thermal current at the emitter and collector,reaching its promise for large thermal amplification.The competition between the quantum coherence and the incoherence induces a significant variation in the amplification factor and consequently relates the thermal controls with quantum effects.The results obtained here will provide a feasible scheme for the realization of quantum thermal management devices.
