Abstract

Quantum logic gates play a significant role as the fundamental building block for both quantum computing and quantum communication processes. The proposed paper highlights the implementation of different Pauli’s quantum gate using silicon nitride-based racetrack configured ring resonator. The polarization rotation is noted at the λ ⁓ 1529.5 nm. The different Pauli’s gate is perceived at the resonance wavelength of 1529.5 nm, by changing the azimuth as well as elliptical angle of the input light. The proposed model is fast and efficient. The proposed polarization driven Pauli’s quantum gate has been validated using the jones matrix and numerical simulation.
