Fermionic quantum gates in optical lattices — •Timon Hilker — University of Strathclyde, Glasgow, UK

A fermionic quantum computer uses the occupation of Fermionic modes instead of qubits as the fundamental unit. Such a quantum computer would allow us to run quantum simulations of fermions more efficiently than spin-based quantum computers, which have to map fermionic exchange statistics to qubits via an overhead in resources and circuit depth.

Fermionic atoms in optical lattices have long been used successfully for analog quantum simulations. In this talk, I will discuss how to digitalise the motion and interaction of atoms with gates, and I will indicate how these can extend the current simulations of the Fermi Hubbard model towards hybrid analog-digital simulations, non-local interactions, and applications from material science and quantum chemistry.
