Patent ID: 8837544

Claim:
A quantum optical device comprising: a first resonator; a defect structure containing a first defect, wherein a transition between quantum states associated with the first defect produces electromagnetic radiation in the first resonator; a first tuning structure positioned to interact with the electromagnetic radiation in a resonant mode of the first resonator so that a frequency of the resonant mode of the first resonator depends on a characteristic of the first tuning structure, wherein the characteristic of the first tuning structure is adjustable after fabrication of the first resonator; a second resonator optically coupled to a second defect so that a transition between quantum states associated with the second defect produces electromagnetic radiation in the second resonator; and a second tuning structure positioned to interact with the electromagnetic radiation in the second resonator so that a resonant mode of the second resonator depends on a characteristic of the second tuning structure, wherein the characteristic of the second tuning structure is adjustable independently of the characteristic of the first tuning structure.
