论文摘要
从理论上讲，我们提出了一个在腔量子电动力学系统中的光子阻滞方案，该系统由与单模Fabry-Perot腔相互作用的N型原子介质组成。与较大的失谐抑制抑制的非线性非分散诱导的光子阻滞相反，我们方案中的光子阻滞是由N型原子系统产生的空腔的大型非线性耗散引起的。深度光子封锁表现出消失的腔线宽度内相等的二阶相关函数。这项工作提供了有效的光子阻滞，因为它在近谐振情况下起作用。
We theoretically propose a scheme for photon blockade in a cavity quantum electrodynamical system consisting of an N-type atomic medium interacting with a single-mode Fabry-Perot cavity. In contrast to inefficient nonlinear-dispersion-induced photon blockade suppressed by a large detuning, the photon blockade in our scheme is induced by a large nonlinear dissipation of the cavity created by the N-type atomic system. A deep photon blockade is manifested with a vanishing equal-time second-order correlation function within the cavity linewidth. This work provides an efficient photon blockade because it work in the near-resonance case.
