Quantum computing marks a major change in how we process information. It goes beyond the binary limits of classical "bits," which exist only as 0 or 1. Instead, it uses "qubits" that can exist in ...

Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve some problems. A new preprint study shows how ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

Paris-based quantum computing startup Alice & Bob has announced a stunning breakthrough in quantum computing: its qubits can now resist bit-flip errors for more than an hour. That’s four times longer ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

Inside IBM’s main research center rises a maze of silver towers, each 22 feet tall. Through their vented flanks, you catch glimpses of blinking lights and the shadows of wires. The machine’s ...

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today ...
