单光子驱动的腔内弱非线性相移

Intracavity weak nonlinear phase shifts with single photon driving

W. J. Munro, K. Nemoto, G. J. Milburn

摘要:

研究了一种含有克尔非线性介质的双谐振腔,该介质通过交叉相位调制耦合两个模。其中一种模式由单光子脉冲场驱动,另一种模式由相干态驱动。我们发现相干光束交叉相移的内在相位噪声机制可以归结为单光子从腔中发射时间的随机性。讨论了在弱非线性相位门中的应用。

英文摘要:

We investigate a doubly resonant optical cavity containing a Kerr nonlinear medium that couples two modes by a cross phase modulation. One of these modes is driven by a single photon pulsed field, and the other mode is driven by a coherent state. We find an intrinsic phase noise mechanism for the cross phase shift on the coherent beam which can be attributed to the random emission times of single photons from the cavity. An application to a weak nonlinearity phase gate is discussed.
