China unveiled its most advanced quantum computer to date on Thursday, marking cutting another notch in the nation’s push to lead the global race in quantum computing, according to a statement from the Chinese Academy of Sciences, which appears to reflect preliminary information from the Xinhua News Agency, the official state news agency of the People’s Republic of China. CAS’s announcement appears to build on news of the delivery of the chip earlier this spring. The “Tianyan-504,” equipped with a 504-qubit chip named “Xiaohong,” was launched by the China Telecom Quantum Group (CTQG) in partnership with the Chinese Academy of Sciences and QuantumCTek Co., Ltd., the statement reports. The development of the “Tianyan-504” sets a new domestic record, surpassing the 500-qubit threshold—a measure of the computer’s capacity to process quantum information, according to the statement. Quantum computers, unlike traditional computers, use quantum bits, or qubits, which can exist in multiple probabilistic states that theoretically allows them to tackle certain task faster than their classical counterparts. This could allow them, for example, the capabilities to outperform classical machines in certain calculations required for tasks, such as cryptography, material simulation and optimization problems.
