Ye's group operates the world's most precise strontium optical lattice clocks (now entanglement-enhanced), pioneered optical frequency combs and cavity-enhanced comb spectroscopy, demonstrated the thorium-229 nuclear clock transition, and studies ultracold polar molecules for precision measurement and quantum science. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/âHz sensitivity.
