Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on narrow tasks, and the stakes are no longer theoretical. The technology promises ...

What is it about quantum computers that makes them more powerful than conventional machines? A new experiment shows that the property of “quantum contextuality” may be a key ingredient. Quantum ...

For the past year, I kept bringing the same story to my editor: quantum computers are on the edge of becoming useful for scientific discovery. Of course, that has always been the goal. The idea of ...

Scientists may have uncovered the missing piece of quantum computing by reviving a particle once dismissed as useless. This particle, called the neglecton, could give fragile quantum systems the full ...

Specifically "the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit." When you purchase through links on our site, we may earn an affiliate ...

IonQ is racing to build a commercializable quantum computer, but it is burning a lot of money. The company just raised $1 billion through a stock offering. The share price is likely to struggle going ...
