As applications of this framework, we utilize a high-density ensemble of nitrogen vacancy (NV) centers in diamond, and experimentally demonstrate significantly improved control over the disordered, interacting many-body spin system. This enabled the first solid state spin ensemble quantum sensor operating beyond the sensitivity limit imposed by interactions between sensing particles, the first full decoupling and interaction engineering of spin-1 dipolar interactions, as well as the observation and understanding of novel dynamical many-body phenomena, including discrete time crystalline order and thermalization dynamics in long-range interacting XXZ spin models. We further explore the use of NV centers for practical sensing applications, by probing embryogenesis in C. elegans with these tools.
