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

    Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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. LÄS MER

  2. 2. Asymptotic Symmetries and Faddeev-Kulish states in QED and Gravity

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :David Gaharia; [2019]
    Nyckelord :Faddeev-Kulish; BMS; Bondi-Metzner-Sachs; Asymptotic Symmetries; Asymptotic States; Wilson Lines; Infrared Divergence; Bloch-Nordsieck; Large Gauge Transformations; Fock; QED; Quantum Electrodynamics; Perturbative Quantum Gravity; PQG; U 1 ; Transformations; Mandelstam Quantization;

    Sammanfattning : When calculating scattering amplitudes in gauge and gravitational theories one encounters infrared (IR) divergences associated with massless fields. These are known to be artifacts of constructing a quantum field theory starting with free fields, and the assumption that in the asymptotic limit (i.e. LÄS MER

  3. 3. Circuit QED devices for probing Majorana zero modes

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Oscar Erlandsson; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Theoretical understanding indicates that Majorana zero modes in solid-state systems could be utilized for fault-tolerant quantum information processing. The ability to reliably detect these excitations, however, remains a challenge and many of their properties are still unknown. LÄS MER

  4. 4. The Effect of Cognitive Workload on Shooting Performance and Quiet Eye Duration

    Magister-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Grímur Gunnarsson; [2018]
    Nyckelord :quiet eye; quiet eye duration; shooting performance; Stroop task; cognitive workload; Social Sciences;

    Sammanfattning : This study explored the effect of cognitive workload on shooting performance and quiet eye duration (QED) using a Stroop based handgun-shooting task (Stroop shooting). Furthermore, the difference between the reverse Stroop effect and the traditional Stroop effect when shooting based on the Attentional Control Theory was assessed. LÄS MER
