Abstract

We analytically solve the steady-state model of the two interacted qubits respectively coupling to the nonequilibrium squeezed reservoir. This allows us to study the quantum entanglement, the local quantum uncertainty and the heat current easily. It is shown that the squeezing can effectively control the heat current between the two-qubit system and the reservoir. The large squeezing reduces the nonequilibrium concurrence but the local quantum uncertainty could be increased at low temperature by the squeezing in the asymmetric case. Meanwhile, we show that the same heat current could correspond to various values of entanglement and local quantum uncertainty.
