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 ...

Both superconducting and silicon spin qubits–two of the most popular quantum computing technologies–require extremely low ...

And they are stunning to look at. Superconducting quantum computers look like giant chandeliers, with rows of shiny discs, ...

Quantum Computing develops photonic quantum hardware with cost advantages, scaling hurdles and weak financials. Check out why QUBT stock is a hold.

Supercomputers are unsung heroes—unless you're a nerd like we are, in which case they're probably at least a little bit sung. Share on Facebook (opens in a new window) Share on X (opens in a new ...

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.

As with AI, part of the excitement is driven by the immense leaps that could be made in hard problems by a quantum computer.

A new Swinburne study is addressing a core paradox: if quantum computing is solving problems that cannot be checked by conventional methods, how can we be certain the results are correct? Quantum ...

Quantum computing and neutron star physics are converging on the same hard problem: how to describe matter when gravity and ...

The world of quantum computing has barged into a new frontier: space. A tiny quantum computer housed in a satellite is now in orbit around Earth, ScienceNews reports, residing some 330 miles above our ...

The original version of this story appeared in Quanta Magazine. If there’s one law of physics that seems easy to grasp, it’s the second law of thermodynamics: Heat flows spontaneously from hotter ...
