At the heart of today’s computing future lies a new kind of chip—one that could make quantum computing practical, powerful, and scalable. Scientists have been chasing this dream for decades, but one ...

A device with more than 6000 quantum bits, or qubits, has smashed a previously-held record and is the first step towards building the largest quantum computer yet. Each of these is a neutral caesium ...

Jacob Benestad in front of an experimental setup in the laboratory at the Niels Bohr Institute, University of Copenhagen. This setup is similar to the one used during the group's experiments at the ...

IBM announced plans for its IBM Quantum Starling, a fault-tolerant quantum computer, that brings quantum computing a step closer in a market that has long promised revolutionary capabilities while ...

Quantum computing has long felt like a perpetual promise — a mysteriously powerful technology that’s always “about 10 years away.” If you tuned it out, you weren’t alone. But something has shifted ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

Between Gaithersburg and College Park, Maryland, a single strand of fiber optic cable hangs from utility poles along a route ...

Chinese researchers claim that the launch of Hanyuan-2 represents a major step forward for ...

Part 1 of this series explained what quantum computers actually are. Not just faster versions of regular computers, but a fundamentally different kind of machine that exploits the weird rules of ...

The IBM Thomas J. Watson Research Center in Yorktown Heights feels like the set of a science fiction film, complete with retinal scans required to gain access to certain computer labs. But that once ...
