1. 1. Cosmological Horizons and the Unruh Effect

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Niklas Engelhardt Önne; [2023]
   Keywords : Unruh effect; quantum scalar fields; Bogoliubov transformations; accelerated observers; Minkowski spacetime; cosmological horizons; Rindler observers; special relativity; QFT; Unruh-effekten; skalära kvantfält; Bogoliubov-transformationer; accelererande referenssystem; Minkowski rumtid; kosmologiska horisonter; Rindlerobservatörer; speciell relativitetsteori; QFT;

   Abstract : The black hole information paradox, which states that the evaporation of black holes due to Hawking radiation results in a violation of the conservation of quantum information, is arguably one of the most fundamental problems in all of modern physics. Through the equivalence principle, the essence of the problem can be understood and studied in the context of much simpler flat spacetime (described by the theory of special relativity); in this context the Hawking radiation takes the form of the so-called Unruh effect, a thermal effect in the vacuum of a Minkowski quantum field theory that can be measured by accelerated observers.

3. 2. Introducing Quantum Computation in Education

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Amadeus Hedenskog; [2023]
   Keywords : Quantum computation; Quantum computing; Education;

   Abstract : Quantum Computation is the quest for more efficient technologies. It can in principal be applied to Complex quantum systems, Quantum chemical systems, Cyber-security, Finance and AI. However, the introductory course in Quantum Mechanics at the Luleå University of Technology (F0047T) does not provide an introduction to Quantum Computation. READ MORE

4. 3. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Mohamed Abrash; [2023]
   Keywords : Quantum computing; Qubit; Double quantum dot DQD ; Microwave resonator; Quantum integrated circuits; Sweet spots; Hybrid quantum circuits.; Physics and Astronomy;

   Abstract : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. READ MORE

5. 4. Path Integrals in Quantum Mechanics and Low-Dimensional QFT

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Johanna Adbo; [2023]
   Keywords : QFT; path integrals; quantum mechanics; kvantfältteori; vägintegraler; kvantmekanik;

   Abstract : The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. READ MORE

6. 5. Profinite groups

   University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Author : Juan Moreno Poncela; [2023]
   Keywords : Profinite Groups; Infinite Galois Theory; Mathematics and Statistics;

   Abstract : This thesis provides a comprehensive study of profinite groups, which are fascinating mathematical objects that have attracted significant interest in modern algebraic research. Profinite groups are infinite generalizations of finite groups and share many similarities with them. READ MORE
