  • System and method for dispersion-enabled quantum state control of photons
    Patent number: 10185090
    Abstract: Devices and methods are described for selecting a level of entanglement between two nondegenerate photons. The method may include receiving two non degenerate photons through a single input port of a directional photonic coupler; adjusting one of a first-order coupler dispersion M or a power splitting ratio ?(?00) of the directional optical coupler to select a ??; and, emitting the photons from corresponding output ports of the directional optical coupler, wherein the emitted photons have a spectral entanglement corresponding to the selected ??.
    Type: Grant
