  • Topics in Fault-Tolerant Quantum Computation 

    Dawkins, Hillary (University of Waterloo, 2017-01-12)
    This thesis contains the results of research projects broadly related to the pursuit of universal fault-tolerant quantum computation. We are interested in questions such as which resources are required to achieve a quantum ...
  • Electron transport in semiconducting nanowires and quantum dots 

    Holloway, Gregory (University of Waterloo, 2017-01-10)
    Single electrons confined in electrostatic quantum dots are a promising platform for realizing spin based quantum information processing. In this scheme, the spin of each electron is encoded as a qubit, and can be manipulated ...
  • Conical Designs and Categorical Jordan Algebraic Post-Quantum Theories 

    Graydon, Matthew (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 ...
  • Ultrafast manipulation of single photons using dispersion and sum-frequency generation 

    Donohue, John Matthew (University of Waterloo, 2016-12-01)
    Single photons provide a natural platform for quantum communication and quantum networking, as they can be entangled in many degrees of freedom and maintain coherence over long-distance links. However, while their minimal ...
  • Collective Dynamics in NMR and Quantum Noise 

    Annabestani, Razieh (University of Waterloo, 2016-10-17)
    We introduced an open quantum system model to describe the statistical fluctuations of a spin ensemble in NMR. The model considers an ensemble measurement where the detection coil does not distinguish spins, and accounts ...
  • Symmetric Extendability of Quantum States and the Extreme Limits of Quantum Key Distribution 

    Khatri, Sumeet (University of Waterloo, 2016-10-13)
    We investigate QKD protocols with two-way classical post-processing that are based on the well-known six-state and BB84 signal states. In these QKD protocols, the source (Alice) sends quantum signals to the receiver (Bob), ...
  • The computational power of many-body systems 

    Webb, Zachary (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 ...
  • In vitro test of a potential hypoxic radiosensitizer 

    Mei, Yaowen (University of Waterloo, 2016-09-28)
    Oxygen has long been known as a potent radiosensitizer that can enhance the cell killing effects in aerobic cells, while pruned vasculatures and lack of oxygen in the microenvironment of tumor can cause resistance to ...
  • The Compilation of Reversible Circuits and a New Optimization Game 

    Parent, Alex (University of Waterloo, 2016-09-28)
    The focus of this thesis is reversible circuit compilation. We will explore the use of pebble games for circuit analysis. The usefulness of this technique is demonstrated by finding a new space bound for the Karatsuba ...
  • Exploring the foundation of quantum information in quantum optics 

    Ma, Xian (University of Waterloo, 2016-09-21)
    Quantum information is promising in solving certain computational problems and information security. The power of its speed up and privacy is based on one of the most tested physical theory: quantum mechanics. Many of ...
  • Exact results in QFT: Minimal Areas and Maximal Couplings 

    Toledo, Jonathan (University of Waterloo, 2016-09-14)
    This thesis is devoted to a two-pronged study of non-perturbative quantum field theory. In Part I we focus on the four-dimensional super conformal $\mathcal{N}=4$ Yang Mills theory. We compute smooth Wilson loops and ...
  • Magnetic Ordering of Dipolar Spin Ice in Moderate [111] Field 

    Brian, Yee (University of Waterloo, 2016-09-08)
    This thesis explores the low temperature physics of the macroscopically degenerate system of dipolar spin ice in moderate fields applied along the [111] cubic axis. While most applications of field generically lift the ...
  • Charged Black Hole Solutions in Alternative Theories of Gravity 

    Meiers, Michael (University of Waterloo, 2016-09-06)
    In my thesis, I examine charged black holes in two contexts. The first part covers the formation of something analogous to event horizons for a class of Lorentz-Violating theories which allow for signals to travel faster ...
  • Wavefront assessment and correction of the rat eye for two photon excitation therapies 

    Andrews, Ian (University of Waterloo, 2016-08-31)
    Photodynamic therapy (PDT) is a treatment in which light excites a photosensitive drug to produce oxygen radicals that kills nearby cells. Today, PDT’s is most commonly used application is for the destruction of cancerous ...
  • Quantum key distribution devices: How to make them and how to break them 

    Kaiser, Sarah (University of Waterloo, 2016-08-30)
    As more aspects of modern society depend on digital communication, we increasingly rely on infrastructure that ensures the privacy and security of this communication. Classically, this has been provided by cryptographic ...
  • Exact Results in Supersymmetric Gauge Theory 

    Lamy-Poirier, Joel (University of Waterloo, 2016-08-30)
    Exact results are a key component for understanding any physical theory. Unfortunately in the context of quantum field theory (QFT) they are in general impossible to obtain, and we need some sort of approximations. However ...
  • Surface Dynamics, Glass Transition, and Crystallization of Atactic Polystyrene 

    Chai, Yu (University of Waterloo, 2016-08-29)
    How polymers behave near the glass transition is one of the deepest questions in condensed matter physics. In the past two decades, the surface dynamics, glass transition, and crystallization of polymer thin films have ...
  • Three-Photon Excitation of Rubidium Atoms to Rydberg States in a Room Temperature Vapor Cell 

    Cui, Wei (University of Waterloo, 2016-08-29)
    This thesis presents a method for calculating the absorption of diode lasers in one-photon, two-photon and (Doppler-free) three-photon excitation configurations. The specific three-photon system studied is atomic Rb, 5s1/2 ...
  • Novel Methods in Quantum Error Correction 

    Jochym-O'Connor, Tomas (University of Waterloo, 2016-08-24)
    Quantum error correction is the backbone of fault-tolerant quantum computation, a necessary requirement for any large scale quantum computer. The fault-tolerance threshold theorem has long been a target for experimental ...

    Fisher, Kent (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 ...
