Abstract:		Dmitri V. Averin, Kristian Rabenstein, and Vasili K. Semenov We suggest a new type of the magnetic flux detector which can be optimized with respect to the measurement back-action, e.g., for the situation of quantum measurements. The detector is based on manipulation of ballistic motion of individual fluxons in a Josephson transmission line (JTL), with the output information contained in either probabilities of fluxon transmis-sion/reflection, or time delay associated with the fluxon propagation through the JTL. The detector should make possible non-trivial quantum measurement strategies, including condi-tional measurements demonstrating the wave-function reduction in mesoscopic qubits.
