Programmable Quantum Simulators with Atoms and Ions

Peter Zoller, Center for Quantum Physics, University of Innsbruck, and IQOQI, Austrian Academy of Sciences, Innsbruck, Austria

We discuss a new generation of programmable analog quantum simulators which combine a certain amount of programmability with scalability to large particle numbers.  In this talk we report work from a theory-experiment collaboration with trapped ion platforms with up to fifty qubits/spins, with the goal to develop and demonstrate quantum protocols, addressing questions from the fundamental to the practical. Examples to be discussed include measurement protocols revealing the entanglement structure of the many-body wavefunction, and implementing `optimal' quantum metrology with variational quantum circuits, where quantum simulators act as `programmable quantum sensors'.
