Abstract:
Trapped ion systems are among the promising platforms for quantum computation, simulation, precision measurements, and quantum networks. In such systems, one can achieve a high level of control which is essential for solving hard-to-compute physics problems with very high accuracy. In particular, quantum simulation of complex physics models is one of the direct applications of such systems [1,2,3]. With the combination of single and two-qubit gates, we can implement a variety of Hamiltonians and simulate the time dynamics of a desired initial state. In this seminar, I will present technicalities of trapped ion simulators and discuss quantum simulation results obtained by direct implementation of XY interactions [2], Floquet engineering [4] and via application of variational methods [5,6]. I will present experimental results on the characterizatio
