Hefei-based Guizhen Chip Technology, working with USTC's Ren Xifeng group, has demonstrated on-chip generation of a 4-photon 16-qubit GHZ state and a 4-qubit cluster state, with Grover search at 0.987 average identification probability. The result is a milestone for measurement-based optical quantum computing.
