The Fermi-Hubbard model is the starting point for the simulation of many interesting materials, including high-temperature superconductors. Their modelling is a key motivation for the development of quantum simulators and computers. However, the detection of superconducting pairing correlations has been challenging, both because of their off-diagonal character and because it is difficult to prepare superconducting states. In this talk I will discuss recent work using Quantinuum’s “Helios” trapped-ion quantum computer, in which significant superconducting pairing correlations were measured in three regimes of the Fermi-Hubbard model, both in and away from equilibrium.
