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.

A quantum receiver enhanced by adaptive learning

The quantum receiver is an elementary component in quantum information processing tasks. It aims to extract necessary information from non-orthogonal quantum states. Due to the nature of shot noise, signals carried by electromagnetic ...

Using 'cat states' to realize fault-tolerant quantum computers

Error correction in quantum computers could be simplified by a new protocol proposed by an all-RIKEN team based on "cat states." It could cut the computing resources needed to fix errors to the same level as conventional ...
