A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is.

Scientists have demonstrated that a photonic qubit — a quantum bit powered by a particle of light — can detect and correct its own errors while running at room temperature. They say it is a ...

After 30 months of fast-paced innovation in quantum algorithms, six research groups are hoping to hit paydirt. But there can be only one big winner—if there is a winner at all.

A new quantum system called giant superatoms could protect quantum information and enable entanglement between multiple ...

In the race to achieve quantum computing supremacy, a pure-play firm like D-Wave Quantum Inc. (NYSE: QBTS) must watch out for not only competitors of a similar size and scope but also for much larger ...
