1. 11. Fast dynamics and measurements of single-charge devices

   Författare :Fredrik Persson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resonator; single-electron box; superconducting devices; decoherence; quantum capacitance; Sisyphus resistance; transmon; single-Cooper-pair box; qubit; rf-reflectometry;

   Sammanfattning : In this thesis we present measurements on several different devices, including the single-Cooper-pair box (SCB), the single-electron box, tunable superconducting resonators and so called transmon qubits.By exploiting the quantum capacitance of the SCB, its state was measured by embedding the box in a radio-frequency resonator.

3. 12. Creation and Detection of Single Photons

   Författare :Hatim Azzouz; Mohamed Bourennane; Sergey Cherednichenko; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

   Sammanfattning : A growing number of technologies employ quantum properties in order to produce solutions that surpass the performance of conventional devices, or to execute operations that are fundamentally impossible with classical systems alone. In the field of optical quantum information science, photons are utilized to encode, communicate and manipulate information, making them vitally important. LÄS MER

4. 13. X-ray Spectroscopy of Molecules Driven by Strong IR Fields

   Författare :Freddy Fernandes Guimaraes; Faris Gelmukhanov; Michael Meyer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : The current thesis deals with one important branch of the physics of ultrafast processes, namely modeling of femtosecond nuclear dynamics. We suggest a new type of time resolved spectroscopy, the phase sensitive infrared-x-ray pump probe spectroscopy, which combines rich opportunities of IR laser techniques in quantum control of molecular systems with the site selectivity of x-rays.

5. 14. Pulse Propagation in Nonlinear Media and Photonic Crystals

   Författare :Victor Kimberg; Faris Gelmukhanov; Shaul Mukamel; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photonic Crystals; Nonlinear optics; X-ray spectroscopy; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : The present thesis is devoted to theoretical studies of pulse propagation of light through linear and nonlinear media, and of light-induced nuclear dynamics. The first part of the thesis addresses propagation of light pulses in linear periodical media - photonic crystals. LÄS MER

7. 15. Dynamics of multiphoton processes in nonlinear optics and x-ray spectroscopy
