Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations—virtual photons popping in and out of existence that can interact with matter, giving rise to new, ...

Researchers have now achieved high-Q photonic flatbands that span the entire k-space of nonlocal metasurfaces and can be selectively tailored for linearly polarized or circularly polarized light, ...

A tiny device that entangles light and electrons without super-cooling could revolutionize quantum tech in cryptography, computing, and AI. Present-day quantum computers are big, expensive, and ...

In a major breakthrough, scientists have observed a strange and previously theoretical form of light — known as negative light. This marks the first time in human history that such a phenomenon has ...

Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a single photon can carry. This leap could make quantum communication more ...
