Abstract
Circuits for generating a pair of qudits in a maximally entangled state and methods of operating such circuits are disclosed. The circuits can be photonic circuits that use a combination of beam splitters, phase shifters, and detectors to produce an entangled pair of d-dimensional qudits from an input set of 4d photons. In a case where d equals 2, a pair of qubits in a Bell state can be generated.
