Parallelizing quantum circuit synthesis
(University of Waterloo, 2015-04-24)We present an algorithmic framework for parallel quantum circuit synthesis using meet-in-the-middle synthesis techniques. We also present two implementations thereof, using both threaded and hybrid parallelization ... -
Particle Distributions in a Block Copolymer Nanocomposite
(American Chemical Society, 2008)Self-consistent-field theory is used to predict the center-of-mass distribution of spherical nanoparticles embedded in the lamellar phase of a diblock copolymer melt. The calculation is performed in the dilute limit, where ... -
Path integral Langevin dynamics of complex molecular systems: from low-temperature quantum clusters to biomolecules
(University of Waterloo, 2011-08-31)This thesis presents an implementation of path integral molecular dynamics (PIMD) for sampling equilibrium and dynamical properties within the molecular modelling toolkit (MMTK) [J. Comp. Chem. 21, 79 (2000)], an open ... -
Path Integrals in the Sky: Classical and Quantum Problems with Minimal Assumptions
(University of Waterloo, 2019-10-24)Cosmology has, after the formulation of general relativity, been transformed from a branch of philosophy into an active field in physics. Notwithstanding the significant improvements in our understanding of our Universe, ... -
Peculiar Velocities and Large Scale Flows as Probes of Gravity, ΛCDM and the Growth of Structure over Cosmic Time
(University of Waterloo, 2012-09-28)Peculiar velocities are possibly the most powerful probes of very large-scale mass density fluctuations in the nearby Universe. When coupled with a density field they also can constrain the growth factor of the universe ... -
Periodically-driven quantum many-body systems, many-body localization and machine learning
(University of Waterloo, 2018-03-09)Despite the exponentially large amount of information required in the quantum description of many-body systems, finite size numerical simulations have paved the way for recent progress in the understanding of quantum phases ... -
Perspectives on the Formalism of Quantum Theory
(University of Waterloo, 2012-09-26)Quantum theory has the distinction among physical theories of currently underpinning most of modern physics, while remaining essentially mysterious, with no general agreement about the nature of its principles or the ... -
Photon Rings and Shadow Size for General Integrable Spacetimes
(University of Waterloo, 2023-08-08)According to the no-hair theorem, the unique characteristics of astrophysical black holes are their masses and spins. However, recent observations from the Event Horizon Telescope (EHT) images of M87 and Sgr A* have ... -
Photonic Three-Level Systems Within the Framework of Generalised Probabilistic Theories
(University of Waterloo, 2021-09-24)If one seeks to test quantum theory not against a particular alternative but against many alternatives in a landscape of possibilities, it is crucial to be able to analyze experimental data in a theory-agnostic way. This ... -
Photons & Phonons: A room-temperature diamond quantum memory
(University of Waterloo, 2016-08-19)This thesis presents demonstrations of the storage and manipulation of single photons in a room-temperature diamond quantum memory using a Raman memory protocol. We report on results from four experiments. In the first ... -
Physical Model for Cell Selectivity of Antimicrobial Peptides
(University of Waterloo, 2013-06-20)Antimicrobial peptides (AMPs) are relatively-short chain molecules that living organisms use to defend themselves against a wide range of invading microorganisms such as bacteria and viruses. They selectively bind to and ... -
Physical Properties of Shear Oriented Cocoa Butter
(University of Waterloo, 2008-01-25)Cocoa butter is a highly complex system of triacyglycerides which has been shown to crystallize in a markedly different fashion under the application of shear. A rheometer insert was developed to enable the intact extraction ... -
The Physical Underpinning of Security Proofs for Quantum Key Distribution
(University of Waterloo, 2007-09-27)The dawn of quantum technology unveils a plethora of new possibilities and challenges in the world of information technology, one of which is the quest for secure information transmission. A breakthrough in classical ... -
Physics in Higher-Dimensional Manifolds
(University of Waterloo, 2003)In this thesis, we study various aspects of physics in higher-dimensional manifolds involving a single extra dimension. After giving some historical perspective on the motivation for studying higher-dimensional theories ... -
Physiologically based Pharmacokinetic (PBPK) Modelling of Cisplatin in Rats and Humans
(University of Waterloo, 2019-10-17)The physiologically based pharmacokinetic (PBPK) modelling has been accepted as one of the most effective mechanistic techniques to analyze pharmacokinetics (PK) of drugs in the drug development process. Its effectiveness ... -
Placing Limits on Light Axions with EHT Polarimetry via Closure Traces
(University of Waterloo, 2023-08-31)Black holes can amplify incoming bosonic waves via rotational superradiance, inducing bound states of ultralight bosons around them. This phenomenon has the potential to confine the parameter spaces of new bosons. Axions, ... -
A Polar Decomposition for Quantum Channels: Theory and Applications
(University of Waterloo, 2019-08-23)Every potential benefit of quantum computers would be lost without methods to protect the computations from error. Quantum channels provide a framework for understanding error in quantum systems. In general, for a system ... -
