    "abstract": "We analyze a recent protocol for the transmission of quantum states via a\ndual spin chain [Burgarth and Bose, Phys. Rev. A 71, 052315 (2005)] under the\nconstraint that the receiver\u0027s measurement strength is finite. That is, we\nconsider the channel where the ideal, instantaneous and complete von Neumann\nmeasurements are replaced with a more realistic continuous measurement. We show\nthat for optimal performance the measurement strength must be \"tuned\" to the\nchannel spin-spin coupling, and once this is done, one is able to achieve a\nsimilar transmission rate to that obtained with ideal measurements. The spin\nchain protocol thus remains effective under measurement constraints.",
