New Directions in Quantum Simulation with Trapped Atomic Ions

POSTER

Abstract

The high-degree of isolation and controllability in a trapped ion system makes it a natural platform for quantum simulation. We coherently control and manipulate 15-25 171Yb+ ions confined in a three-layer linear rf Paul trap. Using global Raman beams we engineer tunable spin-spin interactions, which are combined with transverse and longitudinal effective magnetic fields to realize a long-range Ising model. We combine this with a site-dependent effective Bz magnetic field from a tightly focused beam, allowing for initialization of arbitrary product states or creation of a programmable site-dependent field. Harnessing these coherent operations and site-resolved detection, we present recent experiments implemented on this trapped-ion quantum simulator, exploring non-equilibrium phases and toy models of high-energy physics phenomena.
