Abstract
In a general aspect, a photonic quantum network is disclosed. In some implementations, microwave modes and optical modes are generated on first and second quantum processing units (QPUs) by operation of a first transducer device of the first QPU and a second transducer device of the second QPU. The microwave modes are transmitted within the first and second QPUs from the first and second transducer devices to respective first and second qubit devices. The optical modes are transmitted from the first and second QPUs to an interferometer device. By operation of the interferometer device, output signals are generated on respective output channels based on the optical modes from the first and second QPUs. Based on the output signals detected by operation of photodetector devices coupled to the respective output channels, quantum entanglement transferred to the first and second qubit devices by the microwave modes is identified.
