2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/17124We 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 ends of this array. Owing to the Coulomb blockade effect and the effect of dissipative environment on the supercurrent, this circuit enables the gate-controlled transfer of individual Cooper pairs. The first experiment on operating the Al-Cr Cooper pair R-pump is described.Reported at International Workshop on "Macroscopic Quantum Coherence and Computing - MQC2" (14-17 June, 2000, Naples, Italy)SuperconductivityMesoscale and Nanoscale Physicstext
