1. Quantum Interference : Improved Accuracy and Quantum Limits
Sammanfattning : .... LÄS MER
2. Quantum Holonomies : Concepts and Applications to Quantum Computing and Interferometry
Sammanfattning : 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. LÄS MER
3. A quantum for a quantum : Quantum simulators in exotic lattices
Sammanfattning : This thesis centers on how to use exotic lattices in different ways to design potential quantum simulators. These exotic lattices are either real physical objects in the form of ultra cold atoms in bipartite optical lattice systems or lattice models revealed in state space. LÄS MER
4. Quantum State Analysis : Probability theory as logic in Quantum mechanics
Sammanfattning : Quantum mechanics is basically a mathematical recipe on how to construct physical models. Historically its origin and main domain of application has been in the microscopic regime, although it strictly seen constitutes a general mathematical framework not limited to this regime. LÄS MER
5. Open Quantum Systems : Effects in Interferometry, Quantum Computation, and Adiabatic Evolution
Sammanfattning : The effects of open system evolution on single particle interferometry, quantum computation, and the adiabatic approximation are investigated.Single particle interferometry: Three concepts concerning completely positive maps (CPMs) and trace preserving CPMs (channels), named subspace preserving (SP) CPMs, subspace local channels, and gluing of CPMs, are introduced.
