Abstract

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.
