Meeting : Generation of a time-frequency grid state with integrated biphoton frequency combs

Abstract : The GHZ state, whose full name is Greenberger-Horne-Zeilinger state, was proposed by Greenberger, Horne, and Zeilinger in 1989. It is a special entangled state of three quantum bits and is widely defined as a quantum bit system of three or more, with each system being two-dimensional, where the subsystem in state 0 is entangled with all subsystems in state 1. If the state of one quantum bit is measured, the state of the other quantum bits is also determined, and hence it is widely used in the study of entangled states.
