Parent Hamiltonian Reconstruction via Inverse Quantum Annealing

Davide Rattacaso, Gianluca Passarelli, Angelo Russomanno +3

Finding a local Hamiltonian $\hat{\mathcal{H}}$ having a given many-body wavefunction $|\ddot{I}ˆ⟩$ as its ground state, i.e. a parent Hamiltonian, is a challenge of fundamental imp…
