Engineering Efficient Wave-Mixing For High-Fidelity Operations on Kerr-Cat Qubits

ORAL  · Invited

Abstract

The Kerr Parametric Oscillator (KPO) provides a versatile platform for stabilizing and manipulating quantum states of light through engineered nonlinearities and wave-mixing processes. Achieving high-fidelity operations requires not only strong and well-controlled nonlinear interactions, but also chip-level design that enables strong light-matter coupling. In this talk, I will describe the design strategies we developed to implement high-fidelity operations on 2D Kerr-Cat qubits, and our recent progress toward realizing a high-fidelity CZ gate.
