Quantum State Transfer between a Cavity-Photon and an Electron Spin Ensemble of Nitrogen-Vacancy Centers

针对固态杂化体系的量子信息处理,研究了传输线腔场光子与氮空位电子自旋之间的量子态相干传递.通过调控经典微波外场诱导的量子态转变频率,采用受激拉曼绝热渡跃的方法,可以有效地执行光子数态与自旋系综间的态传递操作.基于当前可取的参量,数值计算结果表明本方案为研究量子态传递提供了一种有效的途径.

For quantum information processing with solid- state hybrid systems,we investigate quantum state the coherent state transfer between a cavity-photon of transmission- line resonator and electron spins of nitrogen-vacancy centers. Through adjusting the quantum state transition frequency caused by a classical microwave field,the desired quantum state transfer between a cavity-photon and an electron spin ensemble can be effectively implemented by means of the stimulated Raman adiabatic passage. Moreover,according to the available parameters,numerical simulations show that the proposed scheme can provide an effective approach to study quantum state transfer.
