1. Quantum Holonomies : Concepts and Applications to Quantum Computing and Interferometry
Abstract : Quantum holonomies are investigated in different contexts.A geometric phase is proposed for decomposition dependent evolution, where each component of a given decomposition of a mixed state evolves independently. It is shown that this geometric phase only depends on the path traversed in the space of decompositions. READ MORE

2. Quantum Holonomy for Many-Body Systems and Quantum Computation
Abstract : The research of this Ph. D. thesis is in the field of Quantum Computation and Quantum Information. A key problem in this field is the fragile nature of quantum states. READ MORE

3. Holonomy in Quantum Information Geometry
Abstract : In this thesis we provide a uniform treatment of the two most popular non-adiabatic geometric phases for dynamical systems of mixed quantum states, namely those of Uhlmann and of Sjöqvist et al. We develop a holonomy theory for the latter which we also relate to the already existing theory for the former. READ MORE

4. Entanglement and Quantum Computation from a Geometric and Topological Perspective
Abstract : In this thesis we investigate geometric and topological structures in the context of entanglement and quantum computation.A parallel transport condition is introduced in the context of Franson interferometry based on the maximization of two-particle coincidence intensity. READ MORE

5. Classical Aspects on the Road to Quantum Gravity: A Study in the Framework of the New Variables
Abstract : There has been a lot of progress in the quest for the structure of spacetime since a canonical non-perturbative quantization program for general relativity was set up ten years ago. The crucial ideas are two choices of coordinates on phase space. READ MORE
