“In a GHZ state, if you measure one qubit, the whole superposition collapses. But in a W state, even if you measure one ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

In this era of instant communication and rising cyber attacks, keeping things secret has never been harder. Quantum computers ...

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without ...

USC engineers have developed an optical system that routes light autonomously using thermodynamic principles. Rather than ...

A lead halide material can detect and image single gamma-ray photons with both high-spatial and high-energy resolution ...

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

A cutting-edge experiment led by the University of Zurich and the Hebrew University has made a breakthrough in the search for and understanding of dark ... Due to its thin-layer geometry and ...

Ghost imaging is like a game of Battleship. Instead of seeing an object directly, scientists use entangled photons to remove the background and reveal its silhouette. This method can be used to study ...

Particles similar to axions, the leading candidate for dark matter that has long eluded detection, may have already been ...
