Quantum Computers

Physicists have pushed quantum computing one step closer to becoming a reality.

Acoustics go nano.

The Chinese satellite Micius has once again shattered records, this time enabling practical quantum encryption between Beijing and Austria.

Turns out, there's a quantum speed limit.

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.
