Nanomechanical-resonator-assisted induced transparency in a Cooper-pair box system

We propose a scheme to demonstrate the electromagnetically induced transparency (EIT) in a system consisting of a superconducting Cooper-pair box (CPB) coupled to a nanomechanical resonator (NR). In this scheme, the NR plays an important role to contribute additional auxiliary energy levels to the CPB so that the EIT phenomenon could be realized in such a system. We call it, in this paper, resonator-assisted induced transparency (RAIT). The RAIT technique provides a detection scheme in a real experiment to measure physical properties, such as the vibration frequency and the decay rate, of the coupled NR.
