Title:
RESONATOR AND QUANTUM COMPUTER
Document Type and Number:
Japanese Patent JP2019219667
Kind Code:
A
Abstract:
To increase the success probability of quantum gate operation.SOLUTION: A resonator according to one embodiment comprises a spherical mirror attached to a birefringent crystal that includes a physical system within and a plane mirror attached to a birefringent crystal facing the spherical mirror, and has a resonator mode that combines with the physical system. The birefringent crystal has a first refractive index to a light polarized to a first direction parallel to the direction of polarization in the resonator mode on the optical axis of the resonator and a second refractive index to a light polarized to a second direction parallel to the optical axis and different from the first refractive index, and the equation lA/L=ωπn/λ is satisfied, where l represents the resonator length of the resonator, ω represents the mode west radius of the resonator mode, L represents the total loss per reciprocation of the resonator, A represents the loss per reciprocation of the resonator independent of the resonator length, nrepresents a second refractive index, and λ represents the wavelength of light of the resonator mode.SELECTED DRAWING: Figure 1
