纳米光波导中的非线性量子光学

Nonlinear Quantum Optics in Optomechanical Nanoscale Waveguides

Hashem Zoubi, Klemens Hammerer

摘要:

我们探讨了在纳米级波导中传播的光子之间实现显着的非线性相移的可能性,利用振动模式介导的光子之间的相互作用,并通过受激布里渊散射(SBS)诱导。我们介绍了一种配置,允许通过SBS涉及声波和两个泵浦场的几个数量级的光子减慢。我们提取的条件保持消失的幅度增益或损失缓慢传播的光子,同时保持热声子的影响最小。两个反向传播光子之间的非线性相位可以用来实现确定性相位门。

英文摘要:

We explore the possibility of achieving a significant nonlinear phase shift among photons propagating in nanoscale waveguides exploiting interactions among photons that are mediated by vibrational modes and induced through Stimulated Brillouin Scattering (SBS). We introduce a configuration that allows slowing down the photons by several orders of magnitude via SBS involving sound waves and two pump fields. We extract the conditions for maintaining vanishing amplitude gain or loss for slowly propagating photons while keeping the influence of thermal phonons to the minimum. The nonlinear phase among two counter-propagating photons can be used to realize a deterministic phase gate.
