16. Superconducting qubits - measurement, entanglement, and noise
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
17. Students' depictions of quantum mechanics : a contemporary review and some implications for research and teaching
Sammanfattning : This thesis presents a comprehensive review of research into students’ depictions of quantum mechanics. A taxonomy to describe and compare quantum mechanics education research is presented, and this taxonomy is used to highlight the foci of prior research. A brief history of quantum mechanics education research is also presented. LÄS MER
18. Quantum Dynamics of Molecular Systems and Guided Matter Waves
Sammanfattning : Quantum dynamics is the study of time-dependent phenomena in fundamental processes of atomic and molecular systems. This thesis focuses on systems where nature reveals its quantum aspect; e.g. in vibrational resonance structures, in wave packet revivals and in matter wave interferometry. LÄS MER
19. Quantum technologies for secure communications
Sammanfattning : Quantum technologies promise to revolutionize a variety of fields such as metrology, cryptography or computing, among others. The resources that quantum mechanics offers allow us to design faster optimization algorithms, to provide unconditional security in communications and to measure quantities beyond the grasp of current technology.

20. On relations between classical and quantum theories of information and probability
Sammanfattning : In this thesis we study quantum-like representation and simulation of quantum algorithms by using classical computers.The quantum--like representation algorithm (QLRA) was introduced by A. Khrennikov (1997) to solve the ``inverse Born's rule problem'', i.e. LÄS MER
