Fast and accurate Cooper pair pump

23 Dec 2019 Erdman Paolo Andrea Taddei Fabio Peltonen Joonas T. Fazio Rosario Pekola Jukka P.

We propose a method to perform accurate and fast charge pumping in superconducting nanocircuits. Combining topological properties and quantum control techniques based on shortcuts to adiabaticity, we show that it is theoretically possible to achieve perfectly quantised charge pumping at any finite-speed driving...
