A team of researchers in China has claimed a new record in quantum computing, saying its new computer is far more powerful than any that came before it — including the best effort by the megacorporation Google.
In a preprint uploaded to arXiv, the researchers claim their quantum computer was able to solve a problem using 56 out of its 66 qubits, the quantum equivalent of bits in a conventional computer.
That’s a step up from Google’s Sycamore processor, which only has 54 qubits. In 2019, Google claimed its computer was the first to achieve quantum supremacy, the threshold beyond which quantum computers are able to solve problems that elude classical computers.
