Nanoampere pumping of Cooper pairs
Juha J. Vartiainen, Mikko Mottonen, Jukka Pekola +1
We have employed a tunable Cooper-pair transistor, the sluice, with radio frequency control to pump current over a resistive circuit. We find that the charge transferred per pumpin…

Measurement scheme of the Berry phase in superconducting circuits
Mikko Mottonen, Jukka P. Pekola, Juha J. Vartiainen +2
We present a measurement scheme for observing the Berry phase in a flux assisted Cooper pair pump - the Cooper pair sluice. In contrast to the recent experiments, in which the slui…
