  1. 21. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

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

    Author : Jannek Hansen; [2021]
    Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

  3. 22. Variable selection for generalized linear mixed model by L1 penalization for predicting clinical parameters of ovarian cancer

    University essay from Lunds universitet/Matematisk statistik

    Author : Lan Hoa Diep; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : The quantity of biomarkers, which are proteins in this case, in ovarian cancer (OC) tumor and immune tissue regions of interest (ROIs) were measured with the new technology Digital Spatial Profiler (DSP). These measurements were used to construct regression models on the biomarkers to predict for two clinical parameters; tumor type (”Type 1” vs ”Type 2”) and the immune infiltration type (”Cavities” vs ”Dispersed”).

  4. 23. Optical Study of Micro-Resonators with G-centers as an Active Medium

    University essay from KTH/Tillämpad fysik

    Author : Baptiste Lefaucher; [2021]
    Keywords : G-center; Silicon Photonics; Micro-Resonators Optics; Laser; Photo-Luminescence Spectroscopy; G-center; Kiselfotonik; Mikroresonatoroptik; Laser; Fotoluminescensspektroskopi;

    Abstract : The G-center has recently been identified as the first deterministic single-photon punctual emitter isolated in silicon. This discovery is of great interest for largescale quantum technologies, due to the abilities of silicon in terms of integration and scalability. READ MORE

  5. 24. Towards the detection of single photons in the mid-infrared

    University essay from KTH/Tillämpad fysik

    Author : Bruno Lopez; [2021]
    Keywords : mid-infrared; single-photon; superconducting; nanowire; nanotechnology; quantum technologies; imaging; mitten av infraröd; enfoton; supraledande; nanotråd; nanoteknik; kvantteknologi; avbildning;

    Abstract : In this project, the fabrication of single-photon detectors based on superconducting nanowires is presented, with great focus on extending their operation range to the mid infrared. In particular, Niobium Titanium Nitride (NbTiN) and Molybdenum Silicide (MoSi), superconducting materials with different properties, are presented, studied and used as fabrication platforms.

  6. 25. Asymmetries and Their Impact on Explosively Formed Projectiles Performance

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Kristoffer Seidel; [2021]
    Keywords : ;

    Abstract : Shaped Charges (SC) are explosives which are set up to concentrate the energy of an explosive to deform a thin metal cover, so called liner into either a jet of particles or a solid projectile, the latter one is refered to an Explosively Formed Projectile or EFP. The purpose of this project is to map out the effect of different asymmetries in different parts of the EFP. READ MORE
