The development of 'Jiuzhang 4.0' by the Southern University of Science and Technology signifies a major advancement in quantum computing, potentially accelerating research and development in various technology sectors. This breakthrough could lead to increased investment and innovation in quantum technologies globally, impacting the long-term competitive landscape of the technology industry.
Chinese scientists, led by the Southern University of Science and Technology, have developed 'Jiuzhang 4.0', a programmable quantum computing prototype. This prototype has set a new world record for optical quantum information technology by solving the Gaussian boson sampling problem at a speed more than 10 to the 54th times that of the world's most powerful supercomputer. The team, including professor Lu Chaoyang, manipulated and detected quantum states of up to 3,050 photons, a significant improvement over the previous 'Jiuzhang 3.0'. The findings were published in the journal Nature (journal). This advancement represents a major leap in photonic quantum processors and offers new possibilities for future fault-tolerant optical quantum computing hardware.
