Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are practically impossible to solve. Quantum computers threaten to flip that ...

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. Tim Bajarin covers the tech industry’s impact on PC and CE markets. Two years ago, I spent about six months in deep discussions ...

Quantum computing won’t break Bitcoin in 2026, but the growing practice of “harvest now, decrypt later” is pushing the crypto industry to prepare sooner rather than later. Quantum computing has long ...

Some Bitcoin developers are no longer arguing about whether quantum computing will break the network, but letting onlookers know how long it would take to prepare if it ever did. That shift was ...

Is quantum Bitcoin hacking here? Bitcoin was built on the principle that once funds are secured by a private key, only the holder can access them. But what if that assumption no longer holds? In what ...

Quantum computing’s accelerating breakthroughs are forcing the crypto sector to confront a long-anticipated question. How long before quantum machines can break Bitcoin security? Blockchain analytics ...

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 ...

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.
