A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies ...

Today’s quantum computers are fundamentally impractical. But with a more resilient qubit, scientists believe they can unlock the technology’s extraordinary potential. Soon, they hope to prove it.

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 ...

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 ...

About eight years ago, toward the end of a panel I was moderating on cybersecurity, I turned to the panelists and asked them ...

The quantum computing industry is advancing, but is it advancing fast enough? While we constantly hear claims like a quantum computer could be 20,000 times faster, the actual physical processors — the ...

A compact microwave-photon detector built from a semiconductor double quantum dot and a superconducting cavity could sharpen ...

Ever since Academia Sinica announced a 5-qubit superconducting quantum computer in January 2024, and National Tsing Hua University unveiled a photonic quantum computer capable of integer factorization ...

Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But ...
