Abstract
A phase shifter, a quantum logic gate apparatus, an optical quantum computing apparatus, and a phase shift method, where the phase shifter includes an optical resonant cavity and a quantum point, where a resonance frequency of the optical resonant cavity is ω, the quantum point is located in the optical resonant cavity, and a transition frequency of the quantum point is ω, the quantum point and the optical resonant cavity are coupled to form a coupled system, and a transition energy difference of the coupled system is determined by ω, ω, and a coupling strength between the quantum point and the optical resonant cavity (g), and ωis set.
