    Abstract: A linear optical CZ-gate includes an A1 optical channel having an A1 input end and an A1 output end, an A2 optical channel having an A2 input end and an A2 output end, wherein a first quantum memory is optically coupled to the A2 optical channel, a B1 optical channel having a B1 input end and a B1 output end, wherein a second quantum memory is optically coupled to the B1 optical channel. The A2 optical channel and the B1 optical channel converge at a common optical channel downstream the first quantum memory and the second quantum memory, a nonlinear sign gate optically coupled to the common optical channel, and a B2 optical channel comprising a B2 input end and a B2 output end.

    Abstract: A quantum communications system includes a first quantum repeater and a second quantum repeater each positioned at a repeater node and each having a first quantum memory and a second quantum memory. A first channel switch is optically coupled to the first quantum repeater and a second channel switch is optically coupled to the second quantum repeater. Further, a first sub-channel extends between and optically couples the first channel switch and the first quantum memory of the first quantum repeater, a second sub-channel extends between and optically couples the first channel switch and the first quantum memory of the second quantum repeater, a third sub-channel extends between and optically couples the second channel switch and the second quantum memory of the first quantum repeater, and a fourth sub-channel extends between and optically couples the second channel switch and the second quantum memory of the second quantum repeater.

    Abstract: A quantum computing system that includes a reconfigurable quantum processing unit optically coupled to a photon source and a photon detector and having a plurality of Mach-Zehnder interferometers (MZIs), and a controller communicatively coupled to the plurality of MZIs and configured to generate a control signal to alter a phase setting of at least one of the plurality of MZIs and the plurality of MZIs are configured to alter a phase of one or more photons that traverse the plurality of MZIs. In addition, the quantum computing system includes a quantum memory array having a plurality of quantum memories optically coupled to the plurality of MZIs, where each quantum memory is configured to absorb a photon received by the quantum memory, the received photon including quantum information, and release a photon including the quantum information of the received photon into the reconfigurable quantum processing unit.
