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 ...

One of the current hot research topics is the combination of two of the most recent technological breakthroughs: machine learning and quantum computing. An experimental study shows that already ...

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

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.

IBM's blueprint for hybrid quantum-classical computing architecture may upend the space, generating even more trouble for a quantum-centric firm like D-Wave.

At the time, their technique was a fascinating but impractical creation. Forty years later, it is poised to become an ...
