Vector vortex beams (VVBs) have attracted significant attention in both classical and
quantum optics. Liquid crystal (LC), beyond its applications in information display, has …

We propose an alternative scheme for implementing a two-dimensional (2D) asymmetric
grating with high diffraction intensity in a five-level quantum dots molecules (QDMs) system …

While the existence of disorders is commonly believed to weaken the unique properties of
quantum systems, recent progress has predicted that it can exhibit a counterintuitive …

Quantum illumination and quantum entanglement provide an efficient method for detecting
low-reflectivity targets in bright thermal-noise environments. Until now, almost all studies on …

Hybrid entanglement involving several degrees of freedom or sharing between a discrete
and a continuous degree of freedom, not only increases information capacity, but also …

In this work we study the transverse spatial correlation of the pair of photons generated via
the process of spontaneous parametric frequency down-conversion, in periodically poled …
