Integrated-Optics Quantum Processor Based on Entangled Photons in Coupled Cavities

Abstract

© 2020 IEEE. We propose a scheme of the universal quantum processing unit based on integrated optic waveguide excitation transfer of qubits between optical micro-resonators and Kerr nonlinear interaction between neighboring cavities. We present the protocols for the implementation of single-qubit gates and a two-qubit controlled phase gate. The optimal regimes of gates operation are studied using input-output formalism.
