Didier, N. (author), Pugnetti, S. (author), Blanter, Y.M. (author), Fazio, R. (author)Measuring the quantum dynamics of a mechanical system, when few phonons are involved, remains a challenge. We show that a superconducting microwave resonator linearly coupled to the mechanical mode constitutes a very powerful probe for this scope. This new coupling can be much stronger than the usual radiation pressure interaction by adjusting a...journal article 2011

Didier, N. (author), Blanter, Y.M. (author), Hekking, F.W.J. (author)Recently, a lasing effect has been observed in a superconducting nanocircuit where a Cooper-pair box, acting as an artificial three-level atom, was coupled to a resonator [O. Astafiev, K. Inomata, A. O. Niskanen, T. Yamamoto, Yu. A. Pashkin, Y. Nakamura, and J. S. Tsai, Nature (London) 449, 588 (2007)]. Motivated by this experiment, we analyze...journal article 2010
