Chinese scientists have developed a programmable quantum computing prototype called Jiuzhang 4.0 that has set a new world record for optical quantum information technology, Xinhua reports with reference to a study published in the journal Nature
Led by the University of Science and Technology of China, the team used the prototype to solve the Gaussian boson sampling problem at a speed more than 10 to the 54th times that of the world's most powerful supercomputer. The researchers said they manipulated and detected quantum states of up to 3,050 photons – a significant leap from the 255 photons achieved with the previous Jiuzhang 3.0.
Lu Chaoyang, a professor at the USTC, said the results from Jiuzhang 4.0 represent a major leap in the scale and complexity of low-loss photonic quantum processors, offering new possibilities for constructing ‘trillion-qubit-mode three-dimensional cluster states’ and future ‘fault-tolerant optical quantum computing hardware’.
