Mean-Field Theory of Collective Behavior of Quantum Dipolar Rotors
(University of Waterloo, 2021-02-08)Motivated by the recent experimental measurements of the dielectric property of confined quantum dipolar molecules, the orientational dipolar ordering transition is investigated in the quantum generalization of the quantum ... -
Measuring Entanglement Entropy in Valence Bond Quantum Monte Carlo Simulations
(University of Waterloo, 2010-12-08)In this thesis we examine methods for measuring entanglement entropy in spin-1/2 Heisenberg systems using quantum Monte Carlo in the valence bond basis. We begin by presenting the quantum Monte Carlo techniques used in ... -
Measuring Non-Markovianity of Noise in the Cenrtal Spin System
(University of Waterloo, 2019-05-24)In this thesis, we explore non-Markovian noise in the central spin system due to the coupling between the central spin and the environment. We use a solid state nuclear magnetic resonance system to do the experiment since ... -
Measuring Quantum Correlations of Polarization, Spatial Mode, and Energy-Time Entangled Photon Pairs.

Measuring the Environmental Dependence of Galaxy Haloes with Weak Lensing
(University of Waterloo, 2013-09-04)We investigate the uses of gravitational lensing for analysing the dark matter haloes around galaxies, comparing galaxies within groups and clusters to those in the field. We consider two cases: when only photometric ... -
Measuring Trapped Ion Qudits
(University of Waterloo, 2019-09-26)Quantum information has typically focused on using 2-level qubits to perform simulation and computation. We propose to expand the number of levels for computation using qudits, where \(d>2\). Doing so could be a viable ... -
Membrane-Disrupting Activity of Antimicrobial Peptides and the Electrostatic Bending of Membranes

(University of Waterloo, 2021-12-20)Nowadays, optical communication transmission is based mainly on optical fiber networks. Increasing demands for higher-capacity systems are hampered by signal distortions due to nonlinear effects of the commercial optic ... -
Mode Invisibility Technique - A Quantum Non-Demolition Measurement for Light
(University of Waterloo, 2014-07-14)The act of measuring an observable of a quantum system introduces backaction noise to the measured system. In the most extreme case, the system gets destroyed with its state left unavailable for future measurement. An ... -
Modeling and managing noise in quantum error correction
(University of Waterloo, 2023-10-19)Simulating a quantum system to full accuracy is very costly and often impossible as we do not know the exact dynamics of a given system. In particular, the dynamics of measurement noise are not well understood. For this ... -
