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

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

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

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a ...
