GEOMDISS Work packages
The work is divided into three scientific work packages (WP). WP1 is focused on geometric gates in circuit QED setups, WP2 is focused on geometric pumping of charge in superconducting circuits, and WP3 is focused on geometric effects in quantum dots and nanowires.
The objective of WP2 is to investigate geometric pumping of Cooper pairs in Josephson devices. The main directions of the research are: a) relation between geometric phases (Berry phases) and pumped charge, b) influence of dissipation on the precision of pumping, c) adiabatic vs. non-adiabatic pumping, d) experimental demonstration of the quantization of the current produced by a Cooper pair pump, e) development of a current standard of a sufficiently high precision to close the metrological triangle and be applicable to the redefinition of the international unit system.
