Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem ...

Someday, somebody, somewhere will likely have a quantum computer capable of cracking the fragile codes that underpin every piece of data we exchange over the internet. We don’t know when. It could be ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

IBM is no longer talking about quantum computing as a distant science project. It is laying out a tightly sequenced plan that ...

Quantum computers could revolutionize everything from drug discovery to business analytics—but their incredible power also ...

Universal Quantum has staked its reputation on the trapped-ion approach, allowing it to scale in the quickest and most efficient way, but Webber says the company also believes “there’s a sliver of ...

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 ...

Work has begun on the state’s new multibillion-dollar quantum computing campus on Chicago’s South Side. The lakefront site for the Illinois Quantum and Microelectronics Park was for decades U.S. Steel ...
