For years, quantum computers have been framed as the ultimate problem solvers, machines that would eventually crack any task that classical hardware could not touch. Now a new line of research is ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

As US defence research agency DARPA starts a programme to upend the dominant quantum computing architecture it says will fail ...

Quantum computers are already here, but they make far too many errors. This is arguably the biggest obstacle to the technology really becoming useful, but recent breakthroughs suggest a solution may ...

A new ultra-fast technique allows scientists to track how quickly quantum information disappears. This breakthrough could ...
