Claim 18:
19. A method comprising:
receiving, by a quantum transducer, a set of microwave photons, wherein the quantum transducer comprises:
a tuning component that comprises nonlinear optical material, wherein the nonlinear optical material comprises a centrosymmetric material having a zero second-order nonlinear susceptibility (χ(2)) and a non-zero third-order nonlinear susceptibility (χ(3)),
a microwave resonator, and
an optical resonator,
wherein a first electromagnetic field of the microwave resonator overlaps with a second electromagnetic field of the optical resonator, and the first electromagnetic field and the second electromagnetic field overlap with the centrosymmetric material;

receiving, by the quantum transducer, an input comprising at least one of a voltage pulse or a modulated laser input, wherein the input causes the optical resonator to interact with the microwave resonator and the centrosymmetric material to induce a non-zero second-order nonlinear susceptibility (χ(2)) in the centrosymmetric material;
transducing, by the quantum transducer, based on the interaction the induces the non-zero second-order nonlinear susceptibility (χ(2)) in the centrosymmetric material, the set of microwave photons into a single optical photon; and
outputting, by the quantum transducer, the single optical photon.
