The approach is known for high accuracy, but scaling it up while preserving that accuracy is technically difficult. Helios ...

In the pursuit of powerful and stable quantum computers, researchers at Chalmers University of Technology, Sweden, have developed the theory for an entirely new quantum system – based on the ...

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, ...

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 ...

Quantum computing is becoming an increasingly competitive field, with tech giants including Microsoft, Google and IBM ...

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 Defense Advanced Research Projects Agency is looking for companies to build the hardware and software quantum computers need to communicate and work together. Most quantum computers are standalone ...

Deep inside a data centre in Manhattan, a quantum computer is enshrined in an alcove like an idol. To reach it, visitors pass two sets of sliding doors and banks of the conventional machines it is ...
