Abstract:
A trapped-ion system is one of the most promising platforms for quantum computation, simulation, precision measurements, and quantum networks. In such a system, a high level of control can be achieved, which is essential for solving hard-to-compute physics problems with very high accuracy. In particular, the quantum simulation of complex physics models is one of the direct applications of such systems. A key question in quantum simulation is the validity of simulation results. Significant progress has been made in recent years in predicting the Hamiltonian that governs the time evolution of input states. However, the experimental implementation of these predictions has been technically challenging for large-scale quantum systems. In this seminar, I will present recent results from our lab on learning system Hamiltonians via randomized measurements for systems of up to 51 qubits. Finally, I will demonstrate how to predict simulation results from the learned Hamiltonians.
