In this paper, we derive the bright and dark photon number states for spatial interference of two or more light beams an......

光场的相干性是定量衡量其产生显著的干涉现象所具备的重要物理属性。尽管高时空相干性的激光已成为传统干涉计量与全息成像等领域......

We construct orthogonal Bell states with entangled squeezed vacuum states and show that these states can be discriminate......
