A quantum computer made by researchers in China has solved a calculation in 4.2 hours that would take a classical computer thousands of years. This demonstration of what the researchers call “quantum computational advantage” was made using 6 more qubits – quantum bits – than the computer used by the Google team that first demonstrated the feat in 2019.

Quantum computers have the potential to vastly exceed the abilities of classical computers for certain types of calculations, although classical computers will likely remain far better suited to day-to-day …
