The company’s surface code technique allows its quantum bits to faithfully store and manipulate data for longer, which could pave the way for useful quantum computers.
Google researchers claim to have made a breakthrough in quantum error correction, one that could pave the way for quantum computers that finally live up to the technology’s promise.
Proponents of quantum computers say the machines will be able to benefit scientific discovery in fields ranging from particle physics to drug and materials design—if only their builders can make the hardware behave as intended.
One major challenge has been that quantum computers can store or manipulate information incorrectly, preventing them from executing algorithms that are long enough to be useful. The new research...
