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 method of generating a photon with multiple dimensions includes a step of generating a first photon encoded with quantum information in each of two or more frequency bins and at least one time bin. The method further includes performing a frequency dependent time operation to entangle (i.e. make non-separable) the frequency bins and the time bins in the photon.

摘要： A logic gate device comprising a probe structure having an interface contact, a first logic input for receiving a first light pulse having a first carrier-envelope phase that encodes an input state of the first logic input and a second logic input for receiving a second light pulse having a second carrier-envelope phase that encodes an input state of the second logic input. The probe structure is arranged to be irradiated by the first light pulse to generate a first current component within the probe structure that depends on the first carrier-envelope phase and to be irradiated by the second light pulse to generate a second current component within the probe structure that depends on the second carrier-envelope phase. The interface contact is arranged to output a sum current that comprises the first and second current component, wherein the sum current encodes a logic output state of a logic output.

摘要： A two-photon logic gate introduces a phase shift between two photons using a Q-switched cavity with some nonlinearity. The two-photon logic gate catches photons in and releases photons from de-coupled cavity modes in response to electronic or photonic control signals. This “catch-and-release” two-photon gate can be formed in semiconductor photonic integrated circuit (PIC) that operates at room temperature. When combined with sources, linear circuits, other logic gates, and detectors, it can be used to make a quantum computer with up to 1000 error-corrected logical qubits on a cm2 PIC, with full qubit connectivity to avoid overhead. Two-qubit gate fidelity exceeding 99% is possible with near-term technology, and scaling beyond 99.9% is possible. Two-photon logic gates are also suitable for gate-based quantum digital computing and for analog quantum computing schemes, such as adiabatic quantum computing or quantum annealing.
