Quantum Computers

It's all about smearing your atoms.

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.
