   Sammanfattning : .... LÄS MER

3. 2. Quantum optics in constrained geometries

   Författare :Björn Hessmo; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; quantum optics; atom optics; complementarity; magnetic traps; laser cooling; quantum information; quantal phases; Kvantkemi; Quantum chemistry; Kvantkemi; Quantum Chemistry; kvantkemi;

   Sammanfattning : When light exhibits particle properties, and when matter exhibits wave properties quantum mechanics is needed to describe physical phenomena. A two-photon source produces nonmaximally entangled photon pairs when the source is small enough to diffract light. It is shown that diffraction degrades the entanglement. LÄS MER

4. 3. A quantum for a quantum : Quantum simulators in exotic lattices

   Författare :Pil Maria Saugmann; Jonas Larson; André Eckardt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum physics; condensed matter physics; quantum optics; optical lattices. Fock state lattices; exotic lattices; frustration; Theoretical Physics; teoretisk fysik;

   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

5. 4. Quantum optics with artificial atoms

   Författare :Anton Frisk Kockum; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface acoustic waves; transmon; circuit QED; photon detector; parity measurement; quantum stochastic calculus; Quantum optics; artificial atoms; quantum measurement;

   Sammanfattning : Quantum optics is the study of interaction between atoms and photons. In the eight papers of this thesis, we study a number of systems where artificial atoms (here, superconducting circuits emulating the level structure of an atom) enable us to either improve on known concepts or experiments from quantum optics with natural atoms, or to explore entirely new regimes which have not been possible to reach in such experiments.

7. 5. Quantum Optics and Quantum Information Processing in Rare-Earth-Ion-Doped Crystals

   Författare :Nicklas Ohlsson; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rare-earth ions; Optical processing; Optical storage; Electromagnetism; akustik; optik; Elektromagnetism; optics; acoustics; Photon echo; Quantum optics; Quantum computing; Fysicumarkivet A:2003:Ohlsson;

   Sammanfattning : In this thesis, aspects of the use of cryogenically cooled rare-earth-ion-doped crystals in the fields of quantum optics and quantum information processing are addressed. The experiments and theoretical considerations referred to in this thesis are based on the coherent transient interaction between light and the ions in the crystals. LÄS MER
