The Hadamard gate cannot be replaced by a resource state in universal quantum computation
Benjamin D. M. Jones, Noah Linden, Paul Skrzypczyk
We consider models of quantum computation that involve operations performed on some fixed resourceful quantum state. Examples that fit this paradigm include magic state injection a…

Benchmarking a wide range of optimisers for solving the Fermi-Hubbard model using the variational quantum eigensolver
Benjamin D. M. Jones, Lana Mineh, Ashley Montanaro
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…
