IGNACIO CIRAC LABORATORY - Bounded-Error Quantum Simulation via Hamiltonian and Lindbladian Learning
Ponente: Barbara Kraus (Technical University Munich)Fecha: martes 24 de febrero de 2026 - 15:00Lugar: Aula Naranja, CFTMAT
Resumen:
I will discuss Hamiltonian and Liouvillian learning techniques for analog quantum simulation from non-equilibrium quench dynamics in the limit of weakly dissipative many-body systems [1]. Analog Quantum Simulators offer a route to exploring strongly correlated many-body dynamics beyond classical computation, but their predictive power remains limited by the absence of quantitative error estimation. I will explain a general framework for bounded-error quantum simulation, which provides predictions for many-body observables with experimentally quantifiable uncertainties [2]. I will present the results of a demonstration of this framework on trapped-ion quantum simulators implementing long-range Ising interactions with up to 51 ions.
