Cooper pair tunneling in circuits with substantial dissipation: the three-junction R-pump for single Cooper pairs

A. B. Zorin, S. A. Bogoslovsky, S. V. Lotkhov +1

We propose a circuit comprising a linear array of three small-capacitance superconducting tunnel junctions with miniature resistors (R > R_Q = h/4e^2 = 6.5 kOhm) attached to the en…
