1. 1. Measurement & Feedback Control of a Two Level System

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

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

   Abstract : 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. READ MORE

3. 2. Covering the sphere with noncontextuality inequalities

   University essay from Matematik och tillämpad matematik; Tekniska högskolan

   Author : Sven-Patrik Hallsjö; [2013]
   Keywords : noncontextuality; mathematics; quantum mechanics; bloch sphere;

   Abstract : In this Bachelor’s thesis the following question is answered: Does the inequality posed in the article Klyachko et al [2008] cover the real part of the Bloch surface of a 3D quantum system when used as in Kochen and Specker [1967]? The Klyachko inequality relies on using five measurements to show contextuality of a subset of states on the real part of the Bloch surface. These can now be used in several configurations as present in the Kochen-Specker contextuality proof, by simply rotating the measurements. READ MORE
