1. 1. Continuous Quantum Control of Quantum Dot Systems

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

   Författare :Daniel Holst; [2022]
   Nyckelord :Quantum Control; Quantum Fokker-Planck Master Equation; Maxwell s demon; Quantum dots; Full counting statistics; Generalized Quantum Measurements; Thermodynamics; Physics and Astronomy;

   Sammanfattning : Control and feedback operation of quantum systems have in recent years gained a lot of interest since they are fundamental to achieving functional quantum information processing systems but also of great importance in applications of information to energy conversion within quantum thermodynamics. This thesis has treated a new formalism for feedback control of quantum systems. LÄS MER

3. 2. 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

4. 3. Towards the Formation of the Antihydrogen Molecular Ion

   Magister-uppsats, Stockholms universitet/Fysikum

   Författare :Thomas Nerdi; [2020]
   Nyckelord :Antihydrogen; Resonance Scattering; Non-Hermitian Quantum Mechanics;

   Sammanfattning : The ALPHA experiment at CERN is an ongoing project which tests fundamental symmetries between matter and antimatter by producing and trapping antihydrogen atoms in order to perform precision spectroscopic measurements. A logical next step is to form the antihydrogen molecular ion (consisting of one positron and two antiprotons). LÄS MER

5. 4. Quantum teleportation of single-electron states

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

   Författare :Edvin Olofsson; [2019]
   Nyckelord :Quantum teleportation; Quantum information; Quantum physics; Levitons; Floquet scattering theory; Mesoscopic physics; Nanophysics; Electron quantum optics; Physics and Astronomy;

   Sammanfattning : Quantum teleportation is a way to transfer a quantum state between two locations, by utilizing a shared entangled state, measurements and the ability to communicate measurement outcomes between the two locations. This thesis consists of a theoretical investigation of an experiment that would implement quantum teleportation using single-electron states in mesoscopic architectures. LÄS MER
