Robust Bilayer Charge-Pumping for Spin- and Density-Resolved Quantum Gas Microscopy

Understand

Quantum gas microscopy has emerged as a powerful new way to probe quantum many-body systems at the microscopic level.

• However, layered or efficient spin-resolved readout methods have remained scarce as they impose strong demands on the specific atomic species and constrain the simulated lattice geometry and size.
• Here we present a novel high-fidelity bilayer readout, which can be used for full spin- and density-resolved quantum gas microscopy of two-dimensional systems with arbitrary geometry.
• Our technique makes use of an initial Stern-Gerlach splitting into adjacent layers of a highly-stable vertical superlattice and subsequent charge pumping to separate the layers by $21\,\mu$m.
