Quantum Simulation of Electron Transfer Models with Trapped Ions

ORAL · Invited

Abstract

Laser-cooled trapped ions are a versatile platform for studying out-of-equilibrium dynamics of open quantum systems as they provide highly tunable unitary and non-unitary operations on both internal and external degrees of freedom. In this talk, I will first discuss our recent results [1] on the simulation of molecular electron transfer in a multi-species trapped-ion crystal. We use the hyperfine qubit of a 171Yb+ ion to simulate the electron degree of freedom and the optical qubit of a 172Yb+ ion to perform reservoir engineering on a collective mode encoding a reaction coordinate. This setting allows us to realize a paradigmatic model of molecular electron transfer where we can precisely and independently control the donor-acceptor gap, the electronic and the spin-phonon coupling, and the bath properties. We study the electron transfer dynamics in the nonperturbative regime where there is no clear hierarchy among the energy scales in the model, as it often occurs in biochemical systems [2,3]. I will also show our progress in the construction of a trapped-ion system based on a new monolithic 3D linear trap. Thanks to a combination of laser writing and etching, this trap combines the repeatability and modularity of microfabricated chip traps with the typical advantages of 3D traps, such as eV-deep trapping potentials, robustness to stray fields, larger ion-electrode distance, as well as wider and multi-directional optical access.
