Geometric quantum gates with superconducting qubits
I. Kamleitner, P. Solinas, C. Müller +2
We suggest a scheme to implement a universal set of non-Abelian geometric transformations for a single logical qubit composed of three superconducting transmon qubits coupled to a…
Non-Abelian magnetic monopole in a Bose-Einstein condensate
Ville Pietilä, Mikko Möttönen
Recently, an effective non-Abelian magnetic field with a topology of a monopole was shown to emerge from the adiabatic motion of multilevel atoms in spatially varying laser fields…
Experimental determination of the Berry phase in a superconducting charge pump
Mikko Mottonen, Juha J. Vartiainen, Jukka P. Pekola
We present the first measurements of the Berry phase in a superconducting Cooper pair pump. A fixed amount of Berry phase is accumulated to the quantum-mechanical ground state in e…
Vortex pump for dilute Bose-Einstein condensates
Mikko Mottonen, Ville Pietila, Sami M. M. Virtanen
The formation of vortices by topological phase engineering has been realized experimentally to create the first two- and four-quantum vortices in dilute atomic Bose-Einstein conden…
Heat Transistor: Demonstration of Gate-Controlled Electron Refrigeration
Olli-Pentti Saira, Matthias Meschke, Francesco Giazotto +3
We present experiments on a superconductor-normal metal electron refrigerator in a regime where single-electron charging effects are significant. The system functions as a heat tra…
Stability and dynamics of vortex clusters in nonrotated Bose-Einstein condensates
V. Pietila, M. Mottonen, T. Isoshima +2
We study stationary clusters of vortices and antivortices in dilute pancake-shaped Bose-Einstein condensates confined in nonrotating harmonic traps. Previous theoretical results on…
