Colored noise in Open Quantum Systems: Noisy frequency estimation and control methods
(Universität Ulm, 2019-01-31)
The dynamics of any quantum device is altered by its interaction with the surrounding environment. This thesis discusses the impact of noise in a scenario of quantum frequency estimation and techniques to control the ...
Equilibrium and nonequilibrium aspects of phase transitions in quantum physics
(Universität Ulm, 2018)
Quantum dynamics with trapped ions
(Universität Ulm, 2018-07-19)
Trapped atomic ions are one of the leading platforms for quantum simulations. Recently, they have also established themselves as a testbed for classical statistical mechanics and mesoscopic systems. The challenges in ...
A new quantitative approach to general bosonic environments in open quantum systems : rigorous error bounds and a novel numerical method for finite systems
(Universität Ulm, 2019-09-12)
A Dissertation on open quantum systems, containing a general review of the current standing of the field, in particular regarding systems interacting with Gaussian environments, as well as original analytical and numerical ...
Efficient estimation and verification of quantum many-body systems
(Universität Ulm, 2019-10-17)
Quantum systems and tensors share the property that the complexity of their description grows exponentially with the number of physical subsystems or tensor indices. This thesis discusses efficient methods for tensor ...
