Waiting time distributions in a two-level fluctuator coupled to a superconducting charge detector
Máté Jenei, Elina Potanina, Ruichen Zhao +7
We analyze charge fluctuations in a parasitic state strongly coupled to a superconducting Josephson-junction-based charge detector. The charge dynamics of the state resembles that…
Decay of a Quantum Knot
T. Ollikainen, A. Blinova, M. Möttönen +1
We experimentally study the dynamics of quantum knots in a uniform magnetic field in spin-1 Bose-Einstein condensates. The knot is created in the polar magnetic phase, which rapidl…
Reconstruction Approach to Quantum Dynamics of Bosonic Systems
Akseli Mäkinen, Joni Ikonen, Matti Partanen +1
We propose an approach to analytically solve the quantum dynamics of bosonic systems. The method is based on reconstructing the quantum state of the system from the moments of its…
Calibration of cryogenic amplification chains using normal-metal--insulator--superconductor junctions
Eric Hyyppä, Máté Jenei, Shumpei Masuda +7
Various applications of quantum devices call for an accurate calibration of cryogenic amplification chains. To this end, we present a convenient calibration scheme and use it to ac…
Reservoir Engineering using Quantum Optimal Control for Qubit Reset
Daniel Basilewitsch, Francesco Cosco, Nicola Lo Gullo +4
We determine how to optimally reset a superconducting qubit which interacts with a thermal environment in such a way that the coupling strength is tunable. Describing the system in…
Correlation Picture Approach to Open-Quantum-System Dynamics
S. Alipour, A. T. Rezakhani, A. P. Babu +3
We introduce a new dynamical picture, referred to as correlation picture,' which connects a correlated state to its uncorrelated counterpart. Using this picture allows us to derive…
