New Quantum Processor Surpasses Supercomputers by Quadrillions
A research team from the University of Science and Technology of China (USTC) has unveiled their groundbreaking superconducting quantum computing prototype, Zuchongzhi-3. This innovative system operates on 105 qubits and 182 couplers, achieving a speed that outpaces the world’s fastest supercomputer by a staggering 15 orders of magnitude. Additionally, Zuchongzhi-3 is one million times faster than the latest results published by Google’s quantum processor.
Researchers emphasize that this development marks a significant leap in the performance of quantum computation. Quantum supremacy, the ability of a quantum computer to execute calculations that would take classical supercomputers an impractical duration, has been realized yet again. For context, Google’s Sycamore processor completed a random circuit sampling task in 200 seconds back in 2019. In stark contrast, the latest task completed by USTC’s team took a mere 14 seconds, using advanced classical algorithms and over 1,400 A100 GPUs.
Furthermore, improvements in classical computing enabled the Frontier supercomputer to tackle the same task in just 1.6 seconds, challenging previous claims of quantum superiority. Notably, USTC has been at the forefront of this technological evolution. Their 2020 prototype, Jiuzhang, was the first rigorously proven quantum supremacy demonstration, followed by Zuchongzhi-2 in 2021, which also executed tasks faster than classical systems.
Looking ahead, the USTC team continues to push the boundaries of quantum technology. They are now exploring quantum error correction and various applications in quantum simulation and chemistry. With a coherent time of 72 microseconds and impressive fidelity metrics, Zuchongzhi-3 lays the groundwork for more intricate computations.
Their recent achievements have not gone unnoticed, earning accolades from peers in the scientific community. As one journal reviewer noted, the work represents a significant upgrade from the previous 66-qubit device, Zuchongzhi-2, paving the way for further advancements in the field.
This new processor holds transformative potential for how we approach complex computational problems, ushering in an era where quantum computing could redefine technological possibilities. The progress made by USTC underscores the rapid development in quantum computing, highlighting the interplay between traditional computing and quantum advancements.
