  1. 1. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Andre Nüsslein; [2019]
    Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

    Abstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE

  2. 2. How did Jupiter form?

    University essay from Lunds universitet/Astronomi

    Author : Calle Ahlgren; [2019]
    Keywords : Planet formation; Planet migration; Physics and Astronomy;

    Abstract : Two relatively new concepts in planetary science are planetary migration; wherein the planets migrate through the protoplanetary disk as they form, and pebble accretion; wherein the planetesimals which become terrestrial planets and giant planet cores grow through the accretion of small pebbles. Planetary migration has become a generally accepted concept but there is still much to be learned even about how it affected the formation of our own solar system. READ MORE

  3. 3. Detection of Archaeological Sites from Aerial Imagery using Deep Learning

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Jorge Lazo; [2019]
    Keywords : Deep Learning; Archaeology; Computer Vision; Aerial Imagery; Transfer Learning.; Physics and Astronomy;

    Abstract : In recent years, Deep Learning has proven to be an outstanding tool in the field of computer vision showing promising results in different fields such as the analysis of medical images, obstacle detection for self-driving cars, automatic image caption generation, etc. In the case of Archaeology, the adoption of these methods in the detection of archaeological structures from aerial images has been slower than in other fields.

  4. 4. Single Ion Detection of Cerium in Y2SiO5 Microcrystals

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Vassily Kornienko; [2019]
    Keywords : cerium; YSO; rare-earths; quantum computing; microcrystals; Physics and Astronomy;

    Abstract : Quantum computing with single instances of rare earth-ions doped into inorganic crystals shows great promise as a scalable design in the field of quantum information. A detectable and controllable single readout ion is necessary for the scheme proposed in Lund to work. READ MORE

  5. 5. Noncollinear optical parametric amplification of a supercontinuum

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE
