Title: Measuring geometry and topology of superconducting qubits
Abstract: There is a strong connection between dynamics during slows ramps and the
geometry of the ground state manifold. I will explain this connection and show how it can
be used to measure quantum geometry in a wide class of systems, including an experimental
example of superconducting qubits. By integrating the geometry over a closed parameter
manifold, I will show how one can obtain topological invariants know as Chern numbers in
these simple systems. I will comment on the generalization of these ideas to more
complicated cases such as interacting many- body systems and situations with non-Abelian
connections, all of which should be readily measurable in future experiments.
