Quantum computers, systems that process information leveraging quantum mechanical effects, are expected to outperform ...

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 ...

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.

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems. Imagine a ...

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 ...

That shift arrives as quantum engineers are already scaling machines to thousands of qubits and pushing them to operate at room temperature, while theorists refine the fundamental “speed limits” that ...

If your New Year’s resolution is to understand quantum computing this year, take a cue from a 9-year-old podcaster talking to ...

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 ...

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 ...

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 ...
