Extracting the spin excitation spectrum of a fermionic system using a quantum processor
Understanding low-energy excitations in fermionic systems is crucial for their characterization. They determine the response of the system to external weak perturbations, its dynam...

Benchmarking a wide range of optimisers for solving the Fermi-Hubbard model using the variational quantum eigensolver
We numerically benchmark 30 optimisers on 372 instances of the variational quantum eigensolver for solving the Fermi-Hubbard system with the Hamiltonian variational ansatz. We rank...
