On Magic State Distillation using Nuclear Magnetic Resonance
(University of Waterloo, 2008-01-25)Physical implementations of quantum computers will inevitably be subject to errors. However, provided that the error rate is below some threshold, it is theoretically possible to build fault tolerant quantum computers that ... -
On near-free-surface dynamics of thin polymer films
(University of Waterloo, 2009-04-24)Studies show that dynamical properties of ultra-thin polymer films deviate from those of bulk materials. Despite some controversial issues, there is growing evidence indicating that the interfacial properties play a key ... -
On single-crystal solid-state NMR based quantum information processing
(University of Waterloo, 2010-05-19)Quantum information processing devices promise to solve some problems more efficiently than their classical counterparts. The source of the speedup is the structure of quantum theory itself. In that sense, the physical ... -
On the Classification of the R-separable webs for the Laplace equation in E^3
(University of Waterloo, 2008-04-29)In the first two Chapters I outline the theory and background of separation of variables as an ansatz for solving fundamental partial differential equations (pdes) in Mathematical Physics. Two fundamental approaches will ... -
On The Origin of Cold Molecular Gas In Giant Elliptical Galaxies
(University of Waterloo, 2017-01-23)We present an analysis of 55 giant elliptical galaxies residing in the centre of clusters and groups to investigate the origin of H₂ molecular gas centrally located in these galaxies. Using Chandra X-ray data and IRAM 30m ... -
On the Robustness of Holographic Dualities: AdS Black Holes and Quotient Spaces
(University of Waterloo, 2018-08-10)This dissertation is a collection of works on different topics based on holographic dualities. The dualities studied here are the Kerr/CFT and AdS/CFT correspondence and the researches carried on aim to check their robustness ... -
On-Shell Recursion Relations in General Relativity
(University of Waterloo, 2007-09-11)This thesis is a study of the validity and application of the on-shell recursion relations within the theory of General Relativity. These relations are also known as the Britto-Cachazo-Feng-Witten (BCFW) relations. They ... -
Operational Approaches to Quantum Correlations and Particle Creation in Field Theory
(University of Waterloo, 2015-05-22)In this thesis we examine a variety of question regarding several quantum information-theoretic concepts as they manifest in the context of relativistic quantum fields. In particular, we study the qualitative and quantitative ... -
An Operational Road towards Understanding Causal Indefiniteness within Post-Quantum Theories
(University of Waterloo, 2022-01-07)A theory, whatever it does, must correlate data. We commit ourselves to operational methodology, as a means towards studying the space of Generalised Probability Theories that are compatible with Indefinite Causality. Such ... -
Opposing effects of cationic antimicrobial peptides and divalent cations on bacterial lipopolysaccharides
(American Physical Society, 2017-10-09)The permeability of the bacterial outer membrane, enclosing Gram-negative bacteria, depends on the interactions of the outer, lipopolysaccharide (LPS) layer, with surrounding ions and molecules. We present a coarse-grained ... -
Optical aberrations and cone photoreceptor sampling during normal emmetropization and emmetropization to imposed defocus
(University of Waterloo, 2018-04-23)The eye grows in a coordinated fashion during normal emmetropization which results in an image close to being in focus on the retina for distance vision. Myopia results from the failure of normal emmetropization. Myopia ... -
Optical Biosensing Using Localized Surface Plasmon Resonance of Gold Nanoparticles
(University of Waterloo, 2011-05-25)This thesis describes some experiments developed to probe the fundamental aspects of the interfacial behaviour of proteins. The contents of this thesis can be broadly divided into two parts. In the first part, we ... -
Optical Changes during Normal Emmetropization, Lens-induced Myopia and its Recovery in the Young Chick Eye
(University of Waterloo, 2015-01-20)In human eyes, the at-birth hyperopoic defocus gradually decreases to mild hyperopia or emmetropia at around age 6. Studies on refractive development suggest somewhat complex mechanisms at work between eye power and length. ... -
Optical Design for an Open Access Trapped Ion Quantum Processor
(University of Waterloo, 2021-08-31)The future of quantum information is scaling to a ever larger number of qubits. Doing so will require advances in the approach for all aspects of current experimental systems. The QuantumION project is a large step in this ... -
Optical Fiber Sensors for Temperature and Strain Measurement
(University of Waterloo, 2010-12-09)Optical fiber sensors have already been developed from the experimental stage to practical applications in the past 20 years. There is no doubt that this technology can bring a wealth of applications, ranging from sensors ... -
Optical pulse compression of first anti-Stokes order in the multi-frequency Raman generation with the presence of red shifted shoulder
(University of Waterloo, 2018-09-11)Multi-frequency Raman generation (MRG) is a nonlinear technique to generate intense trains of single-femtosecond pulses. The broad spectrum of different Raman orders which is spread from near-infrared (near-IR) to UV can ... -
Optical Pulse Shaping For Chirped Pulse Interferometry And Bio-Imaging
(University of Waterloo, 2011-09-02)Biomedical imaging requires high resolution to see the fine features of a sample and fast acquisition to observe live cells that move. Optical coherence tomography (OCT) is a powerful technique which uses optical ... -
