    "abstract": "Since quantum feedback is based on classically accessible measurement\nresults, it can provide fundamental insights into the dynamics of quantum\nsystems by making available classical information on the evolution of system\nproperties and on the conditional forces acting on the system. In this paper,\nthe feedback-induced interaction dynamics between a pair of quantum systems is\nanalyzed. It is pointed out that any interaction Hamiltonian can be simulated\nby local feedback if the levels of decoherence are sufficiently high. The\nboundary between genuine entanglement generating quantum interactions and\nnon-entangling classical interactions is identified and the nature of the\ninformation exchange between two quantum systems during an interaction is\ndiscussed.",
