Abstract

Abstract

A flexible model for the control and measurement of NAMRs was introduced.The free Hamiltonian of the dc-SQUID(direct current superconducting quantum interference device) and the interaction Hamiltonian between these two NAMRs and the dc-SQUID by introducing the annihilation and creation operators under the rotating wave approximation were obtained.The mode of the dcSQUID as a classical flied can be treated.In the Heisenberg picture,the generation of two-mode squeezed states of two nanomechanical resonators is shown by their collective coordinate and momentum operators.
- mechanical resonator,
