  • Two dimensional photonic cluster state generator from sequential photons with multiple entanglement gates
    Patent number: 9264148
    Abstract: We describe an integrated waveguide device that creates entanglement between a sequence of periodically spaced (in time) photons in a single input and output mode. The device consists of a polarization maintaining integrated waveguide chip containing a number of delay lines, integrated multimode interferometers with the potential for rapid switching, a polarization controller and off chip computer logic and timing. The device is capable of creating a diverse array of outputs such as linear cluster states and ring cluster states in a single output mode.
    Type: Grant
