摘要： Spin squeezing is a fascinating manifestation of many-particle entanglement and one of the most promising quantum resources. In this paper, we propose a novel realization of a solid-state quantum spin squeezing by applying SiV centers embedded in a diamond waveguide with the help of a microwave field. The phenomena about the generation of spin squeezing are analyzed numerically in Markovian environments. Our analysis shows that spin squeezing can be generated with the microwave field's help under some realistic conditions, despite the presence of dephasing and mechanical damping. This solid-state spin squeezing based on SiV centers in diamonds might be applied to magnetometers, interferometry, and other precise measurements.
