Simulating strongly correlated electronic systems is a significant challenge for classic numerical methods which can be overcome by native quantum systems. Both analog simulators that reconstruct the Hamiltonian and allow reading out snapshots of the wave function, or digital systems where the problem is encoded in a qubit platform have shown impressive results exploring special phases of matter.
In our quantum gas microscope we observe fermionic lithium atoms with single-site and spin resolution. We demonstrate state-of-the-art analog and digital tools, which have recently allowed us to study the universal scaling of correlations in doped Fermi-Hubbard systems at the onset of the pseudogap phase [1], high-fidelity collisional quantum gates [2], and spontaneous strong-to-weak symmetry breaking. With these methods at hand, we are aiming towards measuring signatures of high-temperature superconductivity by using a hybrid analog-digital scheme that allows us to perform basis transformations and thereby enables us to measure more relevant quantities [3].
