Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Entanglement or non-separability constitutes a cornerstone of quantum mechanics from which many of its unique characteristics arise. For example, non-separability in entangled particle pairs leads to ...

Tailoring light is much like tailoring cloth, cutting and snipping to turn a bland fabric into one with some desired pattern. In the case of light, the tailoring is usually done in the spatial degrees ...

A new experiment suggests that we may still need to rely on classical light behavior in order to get its quantum behavior under control. A group of researchers has found that, by generating ...
