Abstract

In this talk, I introduce a protocol for measuring a broad class of observables in fermionic quantum gas microscopes, including long-range superconducting pairing correlations (after a repulsive-to-attractive mapping). Understanding the mechanism of high-temperature superconductivity is a long-standing problem in physics. Quantum simulators promise new insights, however it remains challenging to characterize superconductivity in existing cold-atom experiments.

We theoretically propose a protocol which is experimentally friendly, consisting of pulse sequences of global controls followed by site-resolved particle number measurements, and is designed by analyzing the Hilbert-space structure of dimers of two sites. The protocol is sample efficient and robust to experimental imperfections. Our work serves as a general tool for manipulating quantum states on optical lattices, enhancing their ability to tackle a variety of problems such as high-temperature superconductivity.
