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 ...

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 ...

Optical quantum computers are gaining attention as a next-generation computing technology with high speed and scalability. However, accurately characterizing complex optical processes, where multiple ...

The new quantum computing algorithm, called "Quantum Echoes," is the first that can be independently verified by running it on another quantum computer. When you purchase through links on our site, we ...

A quantum computer has demonstrated that it can solve a problem more efficiently than a conventional computer. This achievement comes from being able to unlock a vast memory resource that classical ...

New estimates suggest it might be 20 times easier to crack cryptography with quantum computers than we thought—but don't panic. Will quantum computers crack cryptographic codes and cause a global ...

Scientists have built a 98-qubit machine that they say performs better than any other quantum computer in the world. They've used it to gain new insights into superconducting physics. When you ...

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...

IBM has just made a major announcement about its plans to achieve large-scale quantum fault tolerance before the end of this decade. Based on the company’s new quantum roadmap, by 2029 IBM expects to ...

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 unveiled Helios, its third-generation ...
