论文摘要
贝尔状态是光子量子信息处理中的基本资源。这些国家在许多光子自由度上成功产生。但是，他们的操纵在动量空间中仍然具有挑战性。在这里，我们提出了一种通过使用空间可变相位对象来设计在横向动量自由度的两光子状态的对称的方案。我们演示了如何通过光子“ bunching”/“ anti Anti-thinging”观测来构建如何构建Hong-Ou-Mandel干涉仪以验证动量纠缠中的对称性。我们还展示了这种方法如何允许生成在交换操作下获得任意阶段的状态。
Bell states are a fundamental resource in photonic quantum information processing. These states have been generated successfully in many photonic degrees of freedom. Their manipulation, however, in the momentum space remains challenging. Here, we present a scheme for engineering the symmetry of two-photon states entangled in the transverse momentum degree of freedom through the use of a spatially variable phase object. We demonstrate how a Hong-Ou-Mandel interferometer must be constructed to verify the symmetry in momentum entanglement via photon "bunching"/"anti-bunching" observation. We also show how this approach allows generating states that acquire an arbitrary phase under the exchange operation.
