Bohmian Mechanics: Towards Illuminating The Quantum Potential
(University of Waterloo, 20180220)This thesis deals with the theoretical and experimental details of trying to understand and infer the quantum potential from Bohmian mechanics using Bohmian trajectories. In this work, some of the key components of the ... 
Causal Discovery of Photonic Bell Experiments
(University of Waterloo, 20200113)A causal understanding of a physical theory is vital. They provide profound insights into the implications of the theory and contain the information required to manipulate, not only predict, our surroundings. Unfortunately, ... 
Causal Models for a Quantum World
(University of Waterloo, 20160518)Quantum mechanics has achieved unparalleled success as an operational theory, describing a wide range of experiments to remarkable accuracy. However, the physical foundations on which it rests remain as puzzling as they ... 
Characterizing Single Photon Emission From Quantum Dots in Nanowires
(University of Waterloo, 20190528)Bright sources of highly indistinguishable single photons are desirable for diverse applications in quantum technology, including quantum cryptographic protocols, information processing, and metrology. The most common ... 
Conical Designs and Categorical Jordan Algebraic PostQuantum Theories
(University of Waterloo, 20170106)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 ... 
An estimation theoretic approach to quantum realizability problems
(University of Waterloo, 20230927)This thesis seeks to develop a general method for solving socalled quantum realizability problems, which are questions of the following form: under which conditions does there exist a quantum state exhibiting a given ... 
Guiding our interpretation of quantum theory by principles of causation and inference
(University of Waterloo, 20210707)A key aim of quantum foundations is to characterize the sense in which nature goes beyond classical physics. Understanding nonclassicality is one of our best avenues towards finding a satisfactory interpretation of quantum ... 
Measuring Quantum Correlations of Polarization, Spatial Mode, and EnergyTime Entangled Photon Pairs.
(University of Waterloo, 20230907)Optical quantum technologies have found applications in all facets of quantum information. Single photons are actively being researched for quantum computation, communication, and sensing, due to their robustness against ... 
Photonic ThreeLevel Systems Within the Framework of Generalised Probabilistic Theories
(University of Waterloo, 20210924)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 theoryagnostic way. This ... 
Photons & Phonons: A roomtemperature diamond quantum memory
(University of Waterloo, 20160819)This thesis presents demonstrations of the storage and manipulation of single photons in a roomtemperature diamond quantum memory using a Raman memory protocol. We report on results from four experiments. In the first ... 
Single photon measurements: from spinorbit lattices to ultrafast pulses
(University of Waterloo, 20210913)Single photons are naturally suited to quantum information processes as they can carry entanglement in multiple degrees of freedom and maintain coherence easily. In order to fully harness single photons for this use, it ... 
Testing classical and quantum theory with single photons
(University of Waterloo, 20180119)To date, quantum theory is the most successful physical theory that has been discovered. However, there is still the possibility that an inconsistency between experimental observations and the predictions of quantum theory ... 
Towards manybody physics with Rydbergdressed cavity polaritons
(University of Waterloo, 20180523)An exciting frontier in quantum information science is the creation and manipulation of bottomup quantum systems that are built and controlled one by one. For the past 30 years, we have witnessed signi cant progresses ... 
Ultrafast manipulation of single photons using dispersion and sumfrequency generation
(University of Waterloo, 20161201)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 longdistance links. However, while their minimal ... 
Ultrafast Metrology in the Quantum Domain
(University of Waterloo, 20190215)Single photons are a natural platform for quantum technologies as they support entanglement in many degrees of freedom and are inherently well protected from a detrimental type of noise called decoherence. In order to ...
