China unveils processor a million times faster than US rival
Chinese scientists have unveiled a new superconducting quantum computing prototype they say operates a million times faster than one of Google's top quantum processors. The Chinese chip is also a quadrillion times more efficient than any conventionally built supercomputer, according to a statement issued by its creators. Dubbed Zuchongzhi-3, the chip was developed by the University of Science and Technology of China (USTC) in cooperation with half a dozen of the nation's scientific institutions. The USTC published the results of its research and the chip's performance analysis in an article for the Physical Review Letters earlier this month. According to the university's statement, the testing showed that the new Chinese processor is a million times faster than Google's Sycamore processor. The US tech giant presented its quantum computer back in October 2024, boasting that it could surpass the fastest conventional supercomputers in performing computationally complex calculations. 'We are focused on developing practical applications for quantum computers that cannot be done on a classical computer,' Google Quantum AI representatives said at the time. The USTC said in its statement that Zuchongzhi-3's computational speed outpaced that of the world's most powerful supercomputer by 15 orders of magnitude (a quadrillion times faster). It is unclear how the newly unveiled chip compares to another Google product – the Willow quantum processor unveiled in December. The two have roughly similar processing capacities, although the Willow is reportedly slightly better than its Chinese rival when it comes to coherence time, a key parameter enabling more complex computations, according to Live Science. The US tech giant has not commented on the USTC statement. Chinese companies have substantially boosted investments in AI and quantum computing after President Xi Jinping urged the nation to accelerate fundamental scientific research. Beijing is aiming to increase self-reliance in crucial areas, including chip-making, space exploration, and military sciences. Bloomberg reported in October 2023 that Chinese companies and institutions applied for 29,853 AI-related patents in 2022, compared to 29,000 in the previous year. The figure is nearly 80% more than US filings.

Did You Know: China's New Quantum Machine Runs One Million Times Faster Than Google's
Email : A revolutionary breakthrough in quantum computing has just been unveiled by the University of Science and Technology of China (USTC), part of the Chinese Academy of Sciences. The team has developed the Zuchongzhi-3, a quantum machine boasting an astonishing 105 qubits and 182 couplers. This new system performs calculations at an unparalleled speed—one million times faster than Google's latest quantum computer and 10¹⁵ times faster than the most powerful supercomputers today. The Zuchongzhi-3 quantum chip, which represents a monumental leap in the race for quantum supremacy, has been developed by a team led by Jianwei Pan, Xiaobo Zhu, Chengzhi Peng, and other researchers. This marks a major advancement from its predecessor, Zuchongzhi-2, and builds on the foundation of China's quantum computing prowess. Breakthrough in Quantum Computing The Zuchongzhi-3 quantum processor pushes the boundaries of what's possible in quantum computing. Operating at speeds that far exceed those of classical supercomputers, Zuchongzhi-3 is a significant step forward in the field of random quantum circuit sampling, a critical task in the journey toward quantum supremacy. In 2019, Google's 53-qubit Sycamore processor claimed quantum supremacy by performing a random circuit sampling task in 200 seconds—an achievement said to take over 10,000 years for the fastest supercomputer at the time. However, in 2023, USTC researchers demonstrated a classical algorithm that completed the same task in just 14 seconds using 1,400 A100 GPUs. The advancement continued with the Frontier supercomputer, which managed to execute the task in just 1.6 seconds, challenging Google's previous claims of quantum supremacy. Jiuzhang and Zuchongzhi: Milestones in Quantum Research The progress didn't stop there. In 2020, USTC researchers made history by achieving quantum supremacy with their Jiuzhang photonic quantum computing prototype, followed by the Zuchongzhi-2 processor in 2021. In 2023, their Jiuzhang-3 system demonstrated quantum supremacy with an astounding 10¹⁶ orders of magnitude better performance than classical supercomputers. With Zuchongzhi-3, the team has now set a new benchmark, surpassing Google's quantum performance by six orders of magnitude. Zuchongzhi-3's Quantum Edge The Zuchongzhi-3 processor's impressive features include 105 qubits, 182 couplers, and a coherence time of 72 microseconds—key for executing more complex operations. The system's single-qubit gate fidelity stands at an exceptional 99.90%, and the two-qubit gate fidelity reaches 99.62%. In a test, the machine completed an 83-qubit, 32-layer random circuit sampling task, showcasing its remarkable computational speed. Advancing Quantum Research With Zuchongzhi-3's success, the research team is now shifting its focus to further advancements in quantum error correction, quantum entanglement, and quantum chemistry. They are working on a 2D grid qubit architecture to enhance qubit interconnectivity, and integrating surface codes for better quantum error correction. The team plans to extend these efforts, with hopes of advancing quantum integration on an even larger scale. The breakthrough has garnered widespread global recognition, with journals praising it as a new benchmark in superconducting quantum computing. As one reviewer noted, 'Zuchongzhi-3 shows state-of-the-art performance and is a significant upgrade from the previous 66-qubit device.' The Future of Quantum Computing
