In 1964, physicist John Bell formulated what became known as Bell's Theorem, showing that if quantum mechanics is correct, ...

Quantum information scientists at the Department of Energy’s Oak Ridge National Laboratory successfully demonstrated a device that combines key quantum photonic capabilities on a single chip for the ...

Imagine the benefits if the entire internet got a game-changing upgrade to speed and security. This is the promise of the quantum internet—an advanced system that uses single photons to operate.

Photons carry information about polarization and also information related to orientation. If we only consider polarization, the result is simple: a single photon can establish at most one bit of ...

Quantum entanglement is a fundamental phenomenon in nature and one of the most intriguing aspects of quantum mechanics. It ...

Sketch of polarization entanglement from an InGaP metasurface. The nanostructured InGaP metasurface enables enhanced generation of polarization-entangled photon pairs counterpropagating along the z ...

Forward-looking: Qunnect, a New York-based company specializing in hardware for scalable quantum networks, has announced significant progress in its quest to build a telecommunications network capable ...
