Exploring Practical Methodologies for the Characterization and Control of Small Quantum Systems
(University of Waterloo, 2018-09-04)
We explore methodologies for characterizing and controlling small quantum systems. We are interested in starting with a description of a quantum system, designing estimators for parameters of the system, developing robust ...
Quantum Indefinite Spacetime: Part II
(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 ...
Concentration Bounds from Parallel Repetition Theorems
(University of Waterloo, 2018-08-22)
This thesis contributes to the study of parallel repetition theorems and concentration bounds for nonlocal games and quantum interactive proofs. We make the following contributions: - A lemma that is useful for converting ...
Entanglement in single-shot quantum channel discrimination
(University of Waterloo, 2018-08-30)
Single-shot quantum channel discrimination is the fundamental task of determining, given only a single use, which of two known quantum channels is acting on a system. In this thesis we investigate the well-known phenomenon ...
