Optimizing Qubit Control Pulses for State Preparation
Annika S. Wiening, Joern Bergendahl, Vicente Leyton-Ortega +1
In the burgeoning field of quantum computing, the precise design and optimization of quantum pulses are essential for enhancing qubit operation fidelity. This study focuses on refi…
Dephasing and pseudo-coherent quantum dynamics in super-Ohmic environments
Philipp Nacke, Florian Otterpohl, Michael Thorwart +1
Dephasing in quantum systems is typically the result of its interaction with environmental degrees of freedom. We investigate within a spin-boson model the influence of a super-Ohm…
The Hidden Phase of the Spin-Boson Model
Florian Otterpohl, Peter Nalbach, Michael Thorwart
A quantum two-level system immersed in a sub-Ohmic bath experiences enhanced low-frequency quantum statistical fluctuations which render the nonequilibrium quantum dynamics highly…
Spectroscopic Signatures of the Dynamical Hydrophobic Solvation Shell Formation
Henning Kirchberg, Peter Nalbach, Christian Bressler +1
When a hydrophilic solute in water is suddenly turned into a hydrophobic species, for instance, by photoionization, a layer of hydrated water molecules forms around the solute on a…
Crossing time in the Landau-Zener quantum dynamics in a super Ohmic environment
Peter Nalbach
We study the dynamics of a quantum two state system driven through an avoided crossing under the influence of a super Ohmic environment, i.e. a longitudinal as well as a transversa…
Quasi-adiabatic path integral approach for quantum systems under the influence of multiple non-commuting fluctuations
Timo Palm, Peter Nalbach
Quantum systems are typically subject to various environmental noise sources. Treating these environmental disturbances with a system-bath approach beyond weak coupling one must re…
