Parent Hamiltonian Reconstruction via Inverse Quantum Annealing
Davide Rattacaso, Gianluca Passarelli, Angelo Russomanno +3
Finding a local Hamiltonian having a given many-body wavefunction as its ground state, i.e. a parent Hamiltonian, is a challenge of fundamental impo…
High-accuracy Hamiltonian learning via delocalized quantum state evolutions
Davide Rattacaso, Gianluca Passarelli, Procolo Lucignano
Learning the unknown Hamiltonian governing the dynamics of a quantum many-body system is a challenging task. In this manuscript, we propose a possible strategy based on repeated me…
Optimal parent Hamiltonians for time-dependent states
Davide Rattacaso, Gianluca Passarelli, Antonio Mezzacapo +2
Given a generic time-dependent many-body quantum state, we determine the associated parent Hamiltonian. This procedure may require, in general, interactions of any sort. Enforcing…
