Quantum Entanglement Creating and Evolving in Two Charge Qubits Coupling to a Nanomechanical Resonator System

We investigate the coupling of two superconducting quantum interference devices （SQUIDs） via a metallic nanomechanical resonator （NAMR）, and bring out the effective interaction between the two SQUIDs. By constructing the evolution operator, we also study the evolvement of entanglement in this compos...

Description
Summary:We investigate the coupling of two superconducting quantum interference devices （SQUIDs） via a metallic nanomechanical resonator （NAMR）, and bring out the effective interaction between the two SQUIDs. By constructing the evolution operator, we also study the evolvement of entanglement in this composed system.
