(260129) -- BEIJING, Jan. 29, 2026 (Xinhua) -- This photo taken on Jan. 21, 2026 shows the Chuang-tzu 2.0, a two-dimensional superconducting processor consisting of 78 qubits, at a lab of the Institute of Physics under the Chinese Academy of Sciences (CAS) in Beijing, capital of China.
Chinese scientists observed a tunable prethermal plateau in a 78-qubit quantum processor, showing how random multipolar driving controls the system's heating before full thermalization.
The study, led by researchers from the Institute of Physics under the CAS and Peking University, was published on Wednesday in the journal Nature. (Xinhua/Jin Liwang)
