Towards Real-World Adoption of Quantum Key Distribution using Entangled Photons
(University of Waterloo, 2012-08-21)In order for quantum key distribution (QKD) to move from the lab to widespread adoption, it will need to be compatible with existing infrastructure. To that end, I demonstrate an implementation of QKD with entangled ... -
Towards simulating 2D effects in lattice gauge theories on a quantum computer
(University of Waterloo, 2020-10-26)Quantum Field Theories (QFTs) are the most successful theories for describing nature at its most fundamental level. Despite the fact that QFTs are capable of predicting a wide range of phenomena, obtaining solutions to ... -
Towards vertex renormalization in 4d Spin Foams
(University of Waterloo, 2017-07-24)A long-standing open problem in 4-dimensional Spin Foam models of Quantum Gravity has been the behavior of the amplitudes under coarse graining. In this thesis, we attempt to study this question by using the recent ... -
Tracing galaxy evolution through the reconstruction of their star formation histories
(University of Waterloo, 2023-05-24)This thesis studies the star formation histories (SFHs) of galaxies in order to understand the nature of 'quenching.' The suppression of star formation, i.e., quenching, over the history of the Universe results in a growing ... -
Transfer Cavity Stabilization Using the Pound-Drever-Hall Technique with Noise Cancellation
(University of Waterloo, 2011-01-24)A system for exciting Rubidium atoms to Rydberg states has been constructed to study the interactions between them and metal surfaces. This thesis describes a method to reach the f Rydberg series using diode lasers. Since ... -
Transition Galaxies: The Evolution of Environmental Quenching
(University of Waterloo, 2021-05-28)We study the evolution of environmental quenching using a photometric selection of transition galaxies in GOGREEN- which encompasses clusters between 1<z<1.5 spanning a wide range in halo mass. We split the galaxies in ... -
Transition Matrix Monte Carlo Methods for Complex Systems
(University of Waterloo, 2019-04-15)The aim of this thesis is to develop efficient transition matrix Monte Carlo simulation methods for complex systems(e.g., spin glasses) that enable one to construct the transition matrix from which the density of states ... -
Transition to light-like trajectories in thin shell dynamics
(Elsevier, 2018-11)It was recently shown that a massive thin shell that is sandwiched between a flat interior and an exterior geometry given by the outgoing Vaidya metric becomes null in a finite proper time. We investigate this transition ... -
