HIGHLIGHTS
- who: Davide Rattacaso and collaborators from the 0126, Italy have published the research work: High-accuracy Hamiltonian learning via delocalized quantum state evolutions, in the Journal: (JOURNAL)
- what: The authors focus on properties of the state (rather than the Hamiltonian) and the authors propose a novel algorithm that requires measurements of a single time-dependent quantum state. Using analytical arguments and numerical examples, the authors show that the accuracy of the method proposed is related to the delocalization of the initial state in the Hamiltonian eigenstates. Scaling to large system sizes is out of the . . .
