1. 41. A Current Need for Continuity

   Magister-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

   Författare :Nils Patrik Svensson; [2022]
   Nyckelord :agential realism; Karen Barad; new materialism; math; infinitesimals; complexity; quantum physics; Copenhagen interpretation; phenomenology; Merleau-Ponty; continuity; Rawls; binary;

   Sammanfattning : Throughout these last few decades, phenomenology and modern physics have slowly started to approach each other in order to bridge the gap between the subjective and objective. In this thesis I aim to show an approach done with the help of Karen Barad's agential realism; a quantum interpretation enabling us to better understand and analyse our complex world, as well as our perception of it.

3. 42. Cold amplification and fiber coupling of a super-conducting nanowire single-photon detector

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Stéphane Cohen; [2022]
   Nyckelord :Applied Physics; Tilllämpad fysik;

   Sammanfattning : Single-photon detectors are an essential tool for quantum photonics: one can harness the quantum properties of single photons for quantum communication as well as use the detectors in low illumination applications.Superconducting nanowire single-photon detectors offer high detection efficiency over a widerange of wavelengths, low dark counts, and a good timing resolution compared to single-photonavalanche diodes.

4. 43. How to Rise from Ashes : A Comprehensive Guide to Finally Understand Canonical Quantization and Build Quantum Mechanics from Scratch

   L3-uppsats, Uppsala universitet/Materialteori; Uppsala universitet/Avdelningen för teoretisk filosofi

   Författare :Karl Herlin; [2022]
   Nyckelord :Quantum mechanics; History of quantum mechanics; Canonical Quantization; double-slit experiment; The Photoelectric Effect; Compton Scattering; Matter Waves; Bohr’s Atomic Model; Old Quantum Theory; Heisenberg-Born-Jordan Matrix Mechanics; Schrodinger’s Quantum Wave Mechanics; equations of motion;

   Sammanfattning : In this review essay, we account for the historical development of canonical quantization. By a detailed review of The Ultraviolet Catastrophe, The Photoelectric Effect, Compton Scattering, Matter Waves and Bohr's Atomic Model we learn about Old Quantum Theory. LÄS MER

5. 44. Full Configuration Interaction Model for 1-D Quantum System

   Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Adam Asaad; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The many-body problem is one of the most challenging problems in physics due to the complexity emerging from the interactions of many quantum particles. Since the advent of computers with increasing power, computational methods have been very successful in providing insight and precise solutions to this problem. LÄS MER

7. 45. Measurement & Feedback Control of a Two Level System

   Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Sayan Ali Khan; [2022]
   Nyckelord :Quantum Measurement; Generalized Measurements; POVM Positive Operator Valued Measure ; Feedback Control; Two-Level System; Physics and Astronomy;

   Sammanfattning : In this bachelor project, the main objective is to investigate how a two-level quantum system can be controlled using weak continuous measurements and feedback control. The Monte-Carlo method was used to simulate the system dynamics under measurement and feedback to investigate how the system state can be controlled. LÄS MER
