    • Applications of the Quantum Kernel Method on a Superconducting Quantum Processor 

      Peters, Evan (University of Waterloo, 2020-05-29)
      The widespread benefits of classical machine learning along with promised speedups by quantum algorithms over their best performing classical counterparts have motivated development of quantum machine learning algorithms ...
    • Coherent delocalization in the light-matter interaction 

      Stritzelberger, Nadine (University of Waterloo, 2020-10-08)
      In this thesis, we study coherent delocalization in the light-matter interaction: we investigate how the coherent center of mass delocalization of a first quantized system affects its interaction with a second quantized ...
    • Decoupling of Information Propagation from Energy Propagation 

      Jonsson, Robert H. (University of Waterloo, 2016-08-31)
      Information and energy are concepts central to our understanding of nature. Their relevance, in physics, ranges from fundamental physics, e.g., in black hole physics, all the way to future quantum computing technology. ...
    • Indirect Quantum Control: An Implementation-Independent Scheme 

      Layden, David (University of Waterloo, 2016-08-17)
      The ability to control quantum systems rapidly as compared to their coherence times is a central requirement for most proposed quantum technologies, such as quantum computing and quantum metrology. Improving the ratio of ...
    • New Aspects of Quantum Interactions: Acceleration-Induced Transparency, Newton’s Cradle Spectra, Superoscillations 

      Šoda, Barbara (University of Waterloo, 2023-01-12)
      We present new results on different aspects of quantum interactions, from new phenomena to new mathematical tools. First, two new phenomena of light-matter interactions are presented: the stimulated Unruh effect and ...
    • Novel Heat-Bath Algorithmic Cooling methods 

      Rodríguez-Briones, Nayeli Azucena (University of Waterloo, 2020-08-20)
      The field of quantum information has inspired new methods for cooling physical systems at the quantum scale by manipulating entropy in an algorithmic way, such as heat-bath algorithmic cooling (HBAC). These methods not ...
    • On Enumerative Structures in Quantum Field Theory 

      Mahmoud, Ali (University of Waterloo, 2020-07-13)
      This thesis addresses a number of enumerative problems that arise in the context of quantum field theory and in the process of renormalization. In particular, the enumeration of rooted connected chord diagrams is further ...
    • On Perturbative Methods in Spectral Geometry 

      Panine, Mikhail (University of Waterloo, 2017-08-28)
      The goal of spectral geometry is to establish how much information about the geometry of compact Riemannian manifolds is contained in the spectra of natural differential operators, especially Laplacians, defined on them. ...
    • On the Application of Bandlimitation and Sampling Theory to Quantum Field Theory 

      Pye, Jason (University of Waterloo, 2020-10-07)
      It is widely believed that combining the uncertainty principle with gravity will lead to an effective minimum length scale. A particular challenge is to specify this scale in a coordinate-independent manner so that covariance ...
    • An Operational Road towards Understanding Causal Indefiniteness within Post-Quantum Theories 

      Sakharwade, Nitica (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 ...
    • Probing Quantum Fields: Measurements and Quantum Energy Teleportation 

      Verdon-Akzam, Guillaume (University of Waterloo, 2017-01-10)
      Quantum Energy Teleportation provides a testbed for modern ideas involving the inter­play between quantum correlations and energy in the quantum thermodynamical regime. In this work, we provide a new class of Quantum Energy ...
    • Quantum Indefinite Spacetime: Part II 

      Jia, Ding (University of Waterloo, 2018-09-10)
      We adopt an operational mode of thinking to study spacetime fluctuations and their impacts on questions of quantum gravity. Particular emphasis is put on studying causal structure fluctuations. The study is guided by the ...
    • Standard model physics from abstract mathematical objects? 

      Furey, Nichol (University of Waterloo, 2016-01-22)
      This thesis constitutes a first attempt to derive aspects of standard model particle physics from purely abstract mathematical objects. We begin abstractly with an algebra, and argue that physical concepts such as particles, ...
    • Toward a theory of everything 

      Jia, Ding (University of Waterloo, 2023-08-21)
      A physical theory of everything is supposed to tell us: (1) The dynamical laws for matter and gravity; (2) The boundary condition of the universe; (3) The relation between the theory and experience. I present a personal ...
    • What is a field, what is a particle? 

      Papageorgiou, Maria-Eftychia (University of Waterloo, 2019-01-25)
      Much of the structure of quantum field theory (QFT) is predicated on the principle of locality. Adherence to locality is achieved in Algebraic QFT (AQFT) by the association of algebras of observables with regions of ...
