Description: High-NA in-situ fluorescence imaging of individual atoms/molecules trapped in optical lattices with single-site resolution.
Bakr pioneered quantum gas microscopy, imaging individual atoms in Hubbard-regime optical lattices with single-site resolution to directly visualize charge, spin, and polaronic correlations in strongly correlated many-body systems, including recent work resolving itinerant spin polarons and the Nagaoka effect in triangular-lattice Hubbard systems. His single-particle/single-molecule-resolved imaging platforms are a borderline but relevant pivot into the quantum-sensing space via ultra-precise, quantum-limited detection of individual quantum particles; included here for review given the emphasis on cutting-edge spatial resolution rather than sensing per se.
Stamper-Kurn's group uses site-resolved quantum-gas microscopy and cavity optomechanics with ultracold atoms to study strongly correlated many-body quantum matter and quantum measurement backaction, techniques that double as some of the most sensitive atom-based force and field sensors available.
Yan built the first quantum gas microscope for ultracold molecules and uses programmable tweezer arrays of fermionic atoms and dipolar molecules to realize custom quantum many-body Hamiltonians (Hubbard and spin models) with single-site resolution. This is primarily a quantum-simulation platform rather than a sensing one, so it is kept as an unpreferred/borderline entry; the same site-resolved tweezer/microscope toolkit underlies emerging proposals for distributed tweezer-array quantum sensors, which is the basis for inclusion.
