5. We consider only the case in which the state of the system can be described as a classical variable, in contrast to so-called "quantum computing devices" [for example, see I. L. Chuang, R. Laflamme, P. W. Shor, W. H. Zurek, Science 270, 1633 (1995) and references therein). These "classical" systems (whose dynamics may nevertheless require quantum-mechanical descriptions) may provide reliable computation even at substantial coupling to the environment.
6. This system was reinvented later as a "flux quantum parametron" [see K. F. Loe and E. Goto, IEEE Trans. Magn. 21, 884 (1985)].

14. Our discussion of entropy transfer serves only as an interpretation of our quantitative result for the energy dissipation, rather than its basis.
