China’s quantum computer harnesses microwaves to challenge Google’s supremacy
Researchers at USTC in China turned to microwave-based error correction to achieve a distance-7 logical qubit, much like ...
Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...
How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...
Quantum bits are fussy and fragile. Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine. In 1994, Peter Shor, a ...
