Hybrid System based on Nitrogen-Vacancy (NV) Center and Spin Wave Device

ORAL

Abstract

We present a hybrid system that offers a promising alternative to semiconductors and MEMS resonators. This hybrid system, combining nitrogen-vacancy (NV) center with spin wave devices, can easily integrate with various substrates. Using the quantum sensing method, we observe spin wave nonlinear response in a micro-size CoFeB waveguide and confirm our results with micromagnetic simulations. Additionally, we demonstrate coherent quantum control of a qubit through nonlinear spin-wave interactions for the first time, constituting a major advance toward miniaturized quantum sensing applications.
