我们考虑非线性光学腔中单光子的动力学。当利用原子暗共振的克尔非线性时，空腔模式可以通过自旋 1/2 哈密顿量很好地描述。我们证明，使用单光子的 pi 脉冲可以实现腔模波函数的相干控制，从而以非常高的精度切换腔的状态。底层物理最好理解为单光子注入/发射事件之间的非线性引起的反相关，我们将其称为光子封锁。我们还提出了一种利用这些强色散相互作用来实现单光子旋转门装置的方法。
We consider the dynamics of single photons in a nonlinear optical cavity. When the Kerr nonlinearities of atomic dark resonances are utilized, the cavity mode is well described by a spin-1/2 Hamiltonian. We show that it is possible to achieve coherent control of the cavity-mode wave function using pi pulses for single photons that switch the state of the cavity with very high accuracy. The underlying physics is best understood as the nonlinearity induced anticorrelation between single-photon injection/emission events, which we refer to as photon blockade. We also propose a method which uses these strong dispersive interactions to realize a single-photon turnstile device.
