Interplay of the inverse proximity effect and magnetic field in out-of-equilibrium single-electron devices
Shuji Nakamura, Yuri A. Pashkin, Mathieu Taupin +11
The magnetic field is shown to affect significantly non-equilibrium quasiparticle (QP) distributions under conditions of inverse proximity effect on the remarkable example of a sin…
Experimental Determination of Dynamical Lee-Yang Zeros
Kay Brandner, Ville F. Maisi, Jukka P. Pekola +2
Statistical physics provides the concepts and methods to explain the phase behavior of interacting many-body systems. Investigations of Lee-Yang zeros --- complex singularities of…
Multiplexing Superconducting Qubit Circuit for Single Microwave Photon Generation
R E George, J Senior, O-P Saira +4
We report on a device that integrates eight superconducting transmon qubits in lambda/4 superconducting coplanar waveguide resonators fed from a common feedline. Using this multipl…
Traceable Coulomb Blockade Thermometry
Ossi Hahtela, Emma Mykkanen, Antti Kemppinen +6
We present a measurement and analysis scheme for determining traceable thermodynamic temperature at cryogenic temperatures using Coulomb blockade thermometry. The uncertainty of th…
Fluctuation Relation for Qubit-Calorimetry
Antti Kupiainen, Paolo Muratore-Ginanneschi, Jukka Pekola +1
Motivated by proposed thermometry measurement on an open quantum system, we present a simple model of an externally driven qubit interacting with a finite sized, fermion environmen…
Nonlocality and dynamic response of Majorana states in fermionic superfluids
I. M. Khaymovich, J. P. Pekola, A. S. Mel'nikov
We suggest a microscopic model describing the nonlocal ac response of a pair of Majorana states in fermionic superfluids beyond the tunneling approximation. The time-dependent pert…
