Fault-tolerant quantum computer memory in diamond

Quantum computing holds the potential to be a game-changing future technology in fields ranging from chemistry to cryptography to finance to pharmaceuticals. Compared to conventional computers, scientists suggest that quantum ...

Team simulates collider physics on quantum computer

Lawrence Berkeley National Laboratory physicists Christian Bauer, Marat Freytsis and Benjamin Nachman have leveraged an IBM Q quantum computer through the Oak Ridge Leadership Computing Facility's Quantum Computing User Program ...

Rats can estimate their timing accuracy

Thanks to their capacity for introspection, human beings are able to estimate the duration of their actions. When they perform a task—especially a time-based task—they can evaluate their performance and correct themselves ...

Quantum errors made more tolerable

ETH physicists have modified one of the major schemes for quantum error correction and put it into practice, demonstrating that they can substantially prolong the lifetime of quantum states—a crucial ingredient for future ...

How big does your quantum computer need to be?

Quantum computers are expected to be disruptive and potentially impact many industry sectors. So researchers in the United Kingdom and the Netherlands decided to explore two very different quantum problems: breaking the encryption ...
