  • Chinese scientists have developed a programmable quantum computing prototype called Zhuzhang

  • 4.0 that has set a new world record for optical quantum information technology.

  • The study has been published in the journal Nature,

  • led by the University of Science and Technology of China.

  • The teen 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 Zhuzhong 3.0.

  • Current mainstream quantum computing technological routes include superconducting, ion trap, photonic, and neutral atom systems.

  • The Zhuzhong series of prototypes encodes quantum bits using photons

  • and performs quantum computation through the manipulation and measurement of these photons.

  • Since its successful construction in 2020,

  • the series has undergone several upgrades, achieving quantum computational advantage,

  • and repeatedly setting world records.
