Sammanfattning : In the early 1980’s, it was suggested that a computer obeying the laws of quantum mechanics would be able to solve problems beyond the capabilities of a classical computer. The novel ways in which such a quantum computer works relies on the quantum properties of the quantum bits (qubits) used to store the information. LÄS MER
Sammanfattning : The research of this Ph. D. thesis is in the field of Quantum Computation and QuantumInformation. A key problem in this field is the fragile nature of quantum states. LÄS MER
4. Dynamics of Quantum Correlations with Photons : Experiments on bound entanglement and contextuality for application in quantum information
Sammanfattning : The rapidly developing interdisciplinary field of quantum information, which merges quantum and information science, studies non-classical aspects of quantum systems. These studies are motivated by the promise that the non-classicality can be used to solve tasks more efficiently than classical methods would allow. LÄS MER
Sammanfattning : In normal and superconducting quantum point contacts there are several sources of fluctuations. Thermally activated impurities in the vicinity of the junction cause the current (or voltage) to change with a typical frequency of the order of one Hz up to a few kHz. LÄS MER
