Physicists take step toward fault-tolerant quantum computing

Some classical computers have error correction built into their memories based on bits; quantum computers, to be workable in the future, will need error correction mechanisms, too, based on the vastly more sensitive qubits.

A new way to share secret information, using quantum mechanics

Quantum information is a powerful technology for increasing the amount of information that can be processed and communicated securely. Using quantum entanglement to securely distribute a secret quantum state among multiple ...

Smart microscopy works out where to take the picture

Is it possible to know exactly where to point a microscope in order to capture the precise moment a bacterium or a virus infects a cell? In order to take high resolution microscopic images of living biological material, you ...

Google hails 'key milestone' in quantum computing

Google scientists said Wednesday they have passed a major milestone in their quest to develop effective quantum computing, with a new study showing they reduced the rate of errors—long an obstacle for the much-hyped technology.
