Quantum Computers

A quantum-encrypted message containing more than one bit of information in each particle of light was beamed through the air between two buildings in a real-life city for the first time.

Scientists have proposed a new way to build a quantum computer using microwaves to control individual atoms, and they say the new method offers a blueprint for a more useful computing machine.

Diamonds may decorate some of the most coveted pieces of bling, but these precious stones could one day have a more practical use: storing vast amounts of data.

Researchers have now performed "quantum teleportation" of laser pulses over several miles within two city networks of fiber optics.

China launched the first-ever quantum satellite Monday (Aug. 15), in an effort to help develop an unhackable communications system.

The technology could usher in a much-anticipated era of quantum computing, which researchers say could help scientists run complex simulations and produce rapid solutions to tricky calculations.

Scientists have for the first time made an advanced machine known as a quantum computer simulate ghostly particles that fluctuate in and out of existence.

The Schrodinger's Cat thought experiment is even weirder than people thought, with the quantum cat trapped in a box able to be alive and dead in two places at once.

A new property of light has been unearthed in bizarre, corkscrew-shaped strips of light.
