  This paper summarizes the recent state of the art of the following topics
presented at the FQMT'04 conference: Quantum, mesoscopic and (partly) classical
thermodynamics; Quantum limits to the second law of thermodynamics; Quantum
measurement; Quantum decoherence and dephasing; Mesoscopic and
nano-electro-mechanical systems; Classical molecular motors, ratchet systems
and rectified motion; Quantum Brownian motion and Quantum motors; Physics of
quantum computing; and Relevant experiments from the nanoscale to the
macroscale. To all these subjects an introduction is given and the recent
literature is broadly overviewed. The paper contains some 450 references in
total.
