The Jiuzhang 2. 0 Photonic Quantum Computer

The research team lead by professor Pan JianWei has upgraded their photonic quantum computer, demonstrating in a new published study phaseprogrammable Gaussian boson sampling (GBS) which produces up to 113 photon detection events out of a 144mode photonic circuit. According to the researchers, the Jiuzhang 2. 0 Photonic Quantum Computer (九章二号) is 10 billion times faster than its earlier version. The study PhaseProgrammable Gaussian Boson Sampling Using Stimulated Squeezed Light was published in the journal Physical Review. Credit: China Media Group(CMG), China Central Television (CCTV)
