Abstract
A quantum state measurement system includes a quantum state generator that generates an optical photon comprising a quantum state. A spectral converter modifies a spectrum of the optical photon and provides the optical photon comprising the quantum state with the modified spectrum. An optical switch switches the optical photon with the modified spectrum to one of a plurality of outputs. A measurement system determines a fidelity of the quantum state of the optical photon with the modified spectrum. A control system provides an electrical control signal to the quantum state generator in response to the determined fidelity of the quantum state that improves a fidelity of at least some subsequent generated optical photons comprising a quantum state that are generated by the quantum state generator after the optical photon.
