Blanket of light may give better quantum computers

Quantum mechanics is one of the most successful theories of natural science, and although its predictions are often counterintuitive, not a single experiment has been conducted to date of which the theory has not been able ...

Quantum physics: Ménage à trois photon-style

Entanglement is one of the properties specific to quantum particles. When two photons become entangled, for instance, the quantum state of the first will correlate perfectly with the quantum state of the second, even if they ...

Thames Humpback whale killed by ship: The casualty of a global problem

A humpback whale was recently spotted in the River Thames near London. This unusual sighting sparked national media interest, similar to "Benny" the beluga who also called the river home for several weeks last year. However, ...

Researchers create first three-photon color-entangled W state

Researchers at the University of Illinois at Urbana-Champaign have constructed a quantum-mechanical state in which the colors of three photons are entangled with each other. The state is a special combination, called a W ...

Quantum vacuum: Less than zero energy

Energy is a quantity that must always be positive—at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then ...

Demonstrating slow light in rubidium vapor using single photons from a trapped ion

Quantum networks can be practically implemented to interface with different quantum systems. In order to photonically link hybrid systems with combined unique properties of each constituent system, scientists must integrate ...
