Title: Superconducting pairing correlations on a 98-qubit trapped-ion quantum computer

Abstract: The Fermi-Hubbard model is the starting point for the simulation of many strongly correlated materials, including high-temperature superconductors, whose 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 of the difficulty of preparing 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. I plan to finish with some open problems that need to be solved before quantum computers can solve generic condensed matter problems of this kind.
