Analysis of the Thermal Fisher Information in 2+1 Dimensional Black Hole Spacetimes
(University of Waterloo, 2023-01-24)In the past decade, relativistic quantum information (RQI) has presented itself as a promising avenue for examining the interaction between relativistic and quantum effects. This is most commonly achieved by coupling ... -
Aspects of Quantum Field Theory with Boundary Conditions
(University of Waterloo, 2019-08-02)This thesis has two modest goals. The primary goal is to deliver three results involving particle detectors interacting with a quantum field in presence of non-trivial boundary conditions (Dirichlet, Neumann, periodic; ... -
Correlation harvesting in the presence of Unruh and Hawking effects
(University of Waterloo, 2023-07-14)Quantum field theory (QFT) in curved spacetime is a study of quantum fields under the influence of the relativistic motion of particles or spacetime curvature. The famous outcomes of this subject are the Unruh and Hawking ... -
Demonstration of a Tunable Coupler Suitable for Investigating Ultra-strong Coupling Light-matter Interactions in Superconducting Devices
(University of Waterloo, 2022-05-02)One of the most ubiquitous processes in nature is the interaction of matter and an electromagnetic field which is well described using the spin-boson model. These light- matter interactions are specified by an interaction ... -
Design and Implementation of an Entanglement Harvesting Experiment With Superconducting Flux Qubits
(University of Waterloo, 2022-05-16)Recent studies in relativistic quantum information have predicted that it is possible to entangle two qubits tunably coupled to the same quantum field in its vacuum state, by allowing the qubits to couple to the field ... -
Experimental prospects for detecting the quantum nature of spacetime
(University of Waterloo, 2017-09-21)This thesis is concerned with advancing the confrontation between relativistic quantum information (RQI) and experiment. We investigate the lessons that some present-day experiments can teach us about the relationship ... -
The Unruh-DeWitt Detector Model: Modified Dispersion and Nonlinear Couplings
(University of Waterloo, 2021-09-30)In this work, we employ the Unruh-DeWitt (UDW) detector model to various ends. We present applications of this relativistic detector model to quantum optics, including decoherence in optical cavities and non-linear quantum ... -
Unruh-DeWitt detector response along static and circular-geodesic trajectories for Schwarzschild-AdS black holes
(University of Waterloo, 2014-08-26)We present novel methods to numerically address the problem of characterizing the response of particle detectors in curved spacetimes. These methods allow for the integration of the Wightman function, at least in principle, ... -
What can detectors detect?
(University of Waterloo, 2021-01-29)This thesis is focused on using a pair of Unruh-DeWitt detectors, which interact locally with a quantum field, to gain information about properties of the field and the underlying spacetime. First, we consider a massless ...
