摘要： A system includes a first photonic integrated circuit. The circuit includes a qubit encoder configured to receive a spatial-mode qubit and convert the spatial-mode qubit to a temporal-mode qubit and an optical interconnect configured to receive and transmit the temporal-mode qubit. The system further includes a second photonic integrated circuit, itself including a qubit decoder configured to receive the temporal-mode qubit and convert the temporal-mode qubit back into the spatial-mode qubit.

摘要： A system includes a classical computing system and one or more quantum computing chips coupled to the classical computing system. The one or more quantum computing chips includes one or more electro-optic devices. Each electro-optic device includes a substrate, a waveguide disposed on top of the substrate, and a layer stack disposed on top of the waveguide and including a plurality of electro-optic material layers interleaved with a plurality of interlayers. Each electro-optic device further comprising a waveguide core disposed on top of a portion of the layer stack. The plurality of interlayers are characterized by a first lattice structure and the plurality of electro-optic material layers are under tensile stress and are characterized by a second lattice structure and crystallographic phase.

摘要： An electro-optic device includes a substrate and a waveguide on the substrate. The waveguide includes a layer stack including a plurality of electro-optic material layers interleaved with a plurality of interlayers, a waveguide core adjacent to the layer stack, a waveguide cladding layer, and a pair of electrodes in electrical contact with the plurality of electro-optic material layers. The plurality of interlayers maintains a first lattice structure at room temperature and a cryogenic temperature. The plurality of electro-optic material layers maintains a second lattice structure and crystallographic phase at the room temperature and the cryogenic temperature.

摘要： Techniques disclosed herein relate to photon sources with high spectral purity and high brightness. In one embodiment, a photon-pair source includes a pump waveguide, a first resonator coupled to the pump waveguide to couple pump photons from the pump waveguide into the first resonator, a second resonator coupled to the first resonator, and an output waveguide coupled to the second resonator. The second resonator is configured to convert the pump photons into photon pairs. The second resonator and the first resonator are configured to cause a coupling-induced resonance splitting in the second resonator or the first resonator. The second resonator and the output waveguide are configured to couple the photon pairs from the second resonator into the output waveguide. In some embodiments, the photo-pair source includes one or more tuners for tuning at least one of the first resonator or the second resonator.
