Abstract
Section titled āAbstractāWe propose an efficient scheme for transferring quantum states and generating\nentangled states between two qubits of different nature. The hybrid system\nconsists a single nitrogen vacancy (NV) center and a superconducting (SC)\nqubit, which couple to an optical cavity and a microwave resonator,\nrespectively. Meanwhile, the optical cavity and the microwave resonator are\ncoupled via the electro-optic effect. By adjusting the relative parameters, we\ncan achieve high fidelity quantum state transfer as well as highly entangled\nstates between the NV center and the SC qubit. This protocol is within the\nreach of currently available techniques, and may provide interesting\napplications in quantum communication and computation with single NV centers\nand SC qubits.\n
