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.

Quantum computing’s edge looked closer after a hard physics problem seemed beyond classical machines. But a new result shows compressed math and smarter algorithms can match or beat that benchmark, ...

Experts believe quantum computing could lead to breakthroughs in fields like cryptography, finance, science and transportation, and IBM says the technology could solve some problems in minutes or ...

Quantum computing promises a new generation of computers capable of solving problems hundreds of millions of times more quickly than today’s fastest supercomputers. This is done by harnessing spooky ...

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 ...

The biggest difference between these two is funding. IonQ has no core business to fund its operations; it must sign research contracts to do so. As of now, IonQ's quantum business isn't sustainable, ...

Quantum computers are cool. Or rather too cool to be practical at the moment. They promise to solve problems that would take today's fastest supercomputers years, or even centuries, to crack. But they ...

After 30 months of fast-paced innovation in quantum algorithms, six research groups are hoping to hit paydirt. But there can be only one big winner—if there is a winner at all. I’m standing in front ...
