Abstract:

In the last two decades, quantum simulators based on ultracold atoms in optical lattices have successfully emulated strongly correlated condensed matter systems. With the recent development of quantum gas microscopes, these quantum simulators can now control and observe ultracold atoms with single-site resolution. Within the same time period, atomic clocks have also begun to use optical lattices to trap alkaline earth metal atoms such as Sr, and they now interrogate the Sr optical qubit with precision and accuracy at the 1e-18 level. Here, we report on a new quantum simulator that combines quantum gas microscopy with optical lattice clock technology. We trap ultracold Sr atoms in large-mode-volume and highly state-dependent optical lattices to enable new kinds of quantum simulations that emulate strongly-coupled light-matter-interfaces in parameter regimes that are unattainable in real photonic systems. Furthermore, our Quantum Technologies open up new possibilities for neutral-atom quantum computers and optical lattice clocks.
