KIMSchool of Mathematics and Physics, Queen’s University,Belfast BT7 1NN, UnitedKingdomWe provide an extensive discussion on a scheme for Hamiltonian tomography of a spin-chain model that does not require state initialization [Phys. Rev. Lett. 102, 187203(2009)]. The method has spurred the attention of the physics community interested inindirect acquisition of information on the dynamics of quantum many-body systems andrepresents a genuine instance of a control-limited quantum protocol.Keywords: Quantum many-body systems; Hamiltonian tomography; Information flux
