    "abstract": "We address the use of entanglement to improve the precision of generalized\nquantum interferometry, i.e. of binary measurements aimed to determine whether\nor not a perturbation has been applied by a given device. For the most relevant\noperations in quantum optics, we evaluate the optimal detection strategy and\nthe ultimate bounds to the minimum detectable perturbation. Our results\nindicate that entanglement-assisted strategies improve the discrimination in\ncomparison with conventional schemes. A concrete setup to approach performances\nof the optimal strategies is also suggested.",
