Quantum Computers

In an unprecedented feat, physicists packed three qubits into each of six particles. The implications could be staggering.

Pulses of light from infrared lasers can speed up computer operations by a factor of 1 million, and may have opened the door to room-temperature quantum computing.

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.
