    • Sensing the shape of spacetime: detector response and entanglement harvesting in curved space 

      Ng, Keith (University of Waterloo, 2019-01-24)
      This thesis seeks to understand what information Unruh-DeWitt detectors can gain about the structure of spacetime. By coupling to the quantum state of a field on a curved space, the detectors can gain information about ...
    • Thermodynamics and Universality in Anisotropic Higher Curvature Spacetimes 

      Brenna, Wilson (University of Waterloo, 2016-06-16)
      In my thesis, I describe new results in the thermodynamics of black holes in two gravitational scenarios: spacetime anisotropy and higher curvature gravity. I focus on classifying the critical point of "Large Black Hole / ...
    • Towards Practical Hybrid Quantum / Classical Computing 

      Edwards, Marcus (University of Waterloo, 2020-09-28)
      Quantum computing is in a critical phase where theoretical schemes and protocols are now being implemented in the real world for the first time. Experimental implementations can help us solidify ideas, and can also complicate ...
    • The Unruh-DeWitt Detector Model: Modified Dispersion and Nonlinear Couplings 

      Sachs, A. Morgan (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 ...
    • What can detectors detect? 

      Henderson, Laura (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 ...
