A method of generating a single photon, includes preparing an optical resonator including a resonator mode of a resonance angular frequency omegac, preparing a material contained in the optical resonator, including a low energy state |g> and a high energy state |e>, and including a transition angular frequency omegaa between |g>-|e> that is varied by an external field, applying, to the material, light of an angular frequency omegal different from the resonance angular frequency omegac, and applying a first external field to the material to vary the transition angular frequency omegaa to resonate with the angular frequency omegal, such that a state of the material is changed to |e>, and then applying a second external field to the material to vary the transition angular frequency omegaa to resonate with the resonance angular frequency omegac, such that the state of the material is restored to |g>.
