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

A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

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 ...

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 ...
