The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university ...

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

Quantum computing is moving from physics labs into real hardware, promising to attack problems that overwhelm even the fastest supercomputers. Among the boldest claims is that these machines could ...

Practical quantum computers, once thought to be decades away, now appear to be much closer than anticipated, thanks to the work of researchers at Caltech and ETH Zurich. Quantum computers are creating ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

Forbes contributors publish independent expert analyses and insights. I write about green energy tech that will change your life. An illustration of quantum entanglement between two particles. The ...

Quantum computers will be able to assume highly complex tasks in the future. With superconducting quantum processors, however, it has thus far been difficult to read out experimental results because ...

A vital ingredient for making quantum computers truly useful just might be conventional computers. That was the message from a gathering of researchers this month, which explained that classical ...

Netherlands-based QuiX Quantum has delivered Carina, the world's first universal photonic quantum computer designed for customer deployment. Unlike most quantum machines, Carina operates at room ...

Quantum computing is challenging everything we thought we knew about technology, time, and even human consciousness. Some scientists theorize that some of the ways quantum computers process ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.
