    "abstract": "We present a protocol to generate and control quantum entanglement between\nthe states of two subsystems (the system ${\\cal S}$) by making measurements on\na third subsystem (the monitor ${\\cal M}$), interacting with ${\\cal S}$. For\nthe sake of comparison we consider first an ideal, or instantaneous projective\nmeasurement, as postulated by von Neumann. Then we compare it with the more\nrealistic or generalized measurement procedure based on photocounting on ${\\cal\nM}$. Further we consider that the interaction term (between ${\\cal S}$ and\n${\\cal M}$) contains a quantum nondemolition variable of ${\\cal S}$ and discuss\nthe possibility and limitations for reconstructing the initial state of ${\\cal\nS}$ from information acquired by photocounting on ${\\cal M}$.",
