Pan Jianwei, a physicist at the University of Science and Technology of China, claims to have built a quantum computer with 60 qubits.
Pan says the computer is a million times faster than Google's Sycamore, which had 54 qubits when it was first developed in 2019. Honeywell announced a computer with 64 qubits in June. Pan revealed his team's development on September 5 during a lecture at Westlake University, Hangzhou, adding that his team had achieved "quantum supremacy."
A greater number of qubits don't necessarily indicate how fast a quantum computer can be. Instead, its superconductivity is measured in fidelity. The Chinese quantum computer is claimed to have 99.5 percent fidelity.
As media outlets in mainland China celebrated the achievement, Pan released a statement on Weibo saying the results were preliminary and there was "no 100 percent guarantee until further verification." His team hasn't yet published a paper on the project.
