Summary:

A new experimental group using alkaline-earth-like atoms in programmable optical tweezer arrays to improve optical-qubit atomic clocks and develop quantum-enhanced metrology and many-body control; actively building the lab and recruiting students and postdocs. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.

Department(s)/lab(s): Physics | Endres Lab @ Caltech
Summary:

The Endres group assembles programmable arrays of individually trapped neutral atoms (Rydberg and alkaline-earth) to advance quantum metrology, entanglement-enhanced optical clocks, and many-body simulation, demonstrating record atom-array optical-clock stability and quantum-enhanced sensing protocols. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.

Department(s)/lab(s): Physics | Kaufman Group (JILA) @ CUBoulder
Summary:

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/√Hz sensitivity.
