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 ...

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 ...

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 ...

With simple arguments, researchers show that nature is complicated! Researchers have made a simple experiment that demonstrates that nature violates common sense. The experiment illustrates that light ...

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 ...
