1. 1. A single trapped Rydberg ion

   Författare :Gerard Higgins; Markus Hennrich; Tilman Pfau; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Trapped ions; Rydberg physics; quantum information platforms; atomic physics; fysik; Physics;

   Sammanfattning : Systems of trapped ions and systems of ultracold Rydberg atoms are used at the forefront of quantum physics research and they make strong contenders as platforms for quantum technologies. Trapped Rydberg ions are a new hybrid technology envisaged to have both the exquisite control of trapped ion systems and the strong interactions of Rydberg atoms. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laserteknik; Laser technology; Atom- och molekylärfysik; Atomic and molecular physics; akustik; optik; Elektromagnetism; optics; acoustics; Electromagnetism; Fysik; Physics; entanglement; spectroscopy; rare-earth-metal-ion-doped crystals spectral hole-burning; inversion; excitation; laser stabilization; quantum computation; quantum gate;

   Sammanfattning : The main aim of this work, was to lay the foundations for the experimental realisation of a quantum mechanical controlled NOT gate in rare-earth-metal-ion-doped crystals. Small amounts of rare-earth elements, added during the growth of some inorganic crystals, will become substituted into the crystal lattice as trivalent ions. LÄS MER

7. 5. The Penning trap mass spectrometer SMILETRAP II and evaporative cooling of highly-charged ions

   Författare :Matthias Hobein; Reinhold Schuch; David Lunney; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Penning trap; Precision mass spectrometry; Atomic mass; Highly-charged ions; Evaporative cooling; Coherent oscillation; Ion beam emittance; Atomic physics; Atomfysik; fysik; Physics;

   Sammanfattning : Accurate mass values have wide-ranging applications in physics and metrology, allowing, for example, to test quantum electrodynamics and fundamental symmetries, to determine fundamental constants, and to establish weight standards. This thesis describes the new high-precision double-Penning trap mass spectrometer SMILETRAP II which aims at relative uncertainties in the mass determination of 10-10 and below. LÄS MER
