Kaufman's group builds programmable optical-tweezer arrays of alkaline-earth atoms (Sr/Yb) that unite atomic-clock precision with entanglement and many-body control, demonstrating tweezer-array optical clocks and entanglement-enhanced metrology. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/âHz sensitivity.
Regal's group laser-cools membrane mechanical oscillators to measure displacement and tiny forces at quantum limits, assembles and entangles single neutral atoms in optical tweezers, and develops optical-to-microwave transduction and atom-based magnetometry - exploring control at the atomic, optical, and mesoscopic quantum frontier. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/âHz sensitivity.
