Complexity in the AdS/CFT correspondence
(University of Waterloo, 2019-08-14)The main goal of this thesis is to carefully analyze aspects of the gravitational quantities conjectured to be dual to quantum complexity in the AdS/CFT correspondence. The two most promising candidates for such holographic ... -
Comprehensive Theoretical Studies of Guided Modes in Multilayer Hybrid Plasmonic Waveguides
(University of Waterloo, 2018-05-02)Plasmonic waveguides (PWs) have integrated the strength of the miniscule size of electrical-wire interconnects and the large operational bandwidth of photonic waveguides. Beyond the diffraction limit, PWs have the ability ... -
Computational Methods for the Measurement of Entanglement in Condensed Matter Systems
(University of Waterloo, 2014-06-19)At the interface of quantum information and condensed matter physics, the study of entanglement in quantum many-body systems requires a new toolset which combines concepts from each. This thesis introduces a set of ... -
The computational power of many-body systems
(University of Waterloo, 2016-09-28)Many-body systems are well known throughout physics to be hard problems to exactly solve, but much of this is folklore resulting from the lack of an analytic solution to these systems. This thesis attempts to classify the ... -
Concepts and methods for benchmarking quantum computers
(University of Waterloo, 2021-07-09)Quantum computers have the potential to bring about a new age of technology, but in order for them to become a reality, the elephant in the room must be addressed, quantum errors. The complexity of quantum errors grows ... -
Conformation of 2-fold Anisotropic Molecules Confined on a Spherical Surface
(University of Waterloo, 2012-03-09)Anisotropic molecules confined on a spherical or other curved surface can display coupled positional and orientational orderings, which make possible applications in physics, chemistry, biology, and material science. ... -
Conical Designs and Categorical Jordan Algebraic Post-Quantum Theories
(University of Waterloo, 2017-01-06)Physical theories can be characterized in terms of their state spaces and their evolutive equations. The kinematical structure and the dynamical structure of finite dimensional quantum theory are, in light of the ... -
Constructing Exact Correlators In N=4 SYM Using Integrability
(University of Waterloo, 2019-08-09)This thesis is devoted to the study of correlation functions in N = 4 superconformal Yang- Mills theory. We focus on a class of four point functions for which we achieve formal results at finite coupling and explicit ... -
Contextuality and Ontological Models: A Tale of Desire and Disappointment
(University of Waterloo, 2019-09-23)Since being defined by Kochen and Specker, and separately by Bell, contextuality has been proposed as one of the key phenomena that distinguishing quantum theory from classical theories. However, with the rise of quantum ... -
Continuous Tensor Networks, Conformal Field Theory and Holography
(University of Waterloo, 2020-07-23)Tensor network methods are playing a central role in multiple disciplines of modern quantum physics, such as condensed matter physics, quantum information and quantum gravity. Based on renormalization group (RG) ideas, ... -
Control and Readout of High-Dimensional Trapped Ion Qudits
(University of Waterloo, 2023-09-07)The trapped ion platform is one of the quantum computing platforms that is at the forefront for realizing large-scale quantum information processing, which is crucial for practically actualizing the advantages of quantum ... -
Control of Light-Matter Interactions in Classical and Quantum Optics
(University of Waterloo, 2018-01-12)In this thesis, we examined a series of techniques for controlling the interaction of light with matter that could be employed to optimize or to control physical phenomena in various potential applications. Some of these ... -
Control techniques in spin based quantum computation
(University of Waterloo, 2019-07-11)Working on quantum systems entail different interests, for example, working on fundamental understanding of quantum systems also lay foundation for better quantum computation techniques. A test for whether a system is ... -
