Quantum state transfer via a hybrid solid-optomechanical interface

摘要

We propose a scheme to implement quantum state transfer between two distant quantum nodes via a hybrid solidoptomechanical interface.The quantum state is encoded on the native superconducting qubit,and transferred to the microwave photon,then the optical photon successively,which afterwards is transmitted to the remote node by cavity leaking,and finally the quantum state is transferred to the remote superconducting qubit.The high efficiency of the state transfer is achieved by controllable Gaussian pulses sequence and numerically demonstrated with theoretically feasible parameters.Our scheme has the potential to implement unified quantum computing-communication-computing,and high fidelity of the microwave-optics-microwave transfer process of the quantum state.
