Flag Fault-Tolerant Error Correction with Qudits
(University of Waterloo, 2022-01-20)In this thesis, I explore fault-tolerant quantum error correction using qudits. I show that a specific flag-fault-tolerant procedure for the five-qubit code may be extended to work on the five qudit code for any prime ... -
Flags and Error Weight Parities: A Development of Fault-tolerant Quantum Computation with Few Ancillas
(University of Waterloo, 2021-10-13)In quantum computation, errors in a quantum circuit arising from its interaction with the environment is one of the biggest obstacles to building large-scale quantum computers. One way to deal with such errors is using ... -
Honest Approximations to Realistic Fault Models and Their Applications to Efficient Simulation of Quantum Error Correction
(University of Waterloo, 2014-04-25)Understanding the performance of realistic noisy encoded circuits is an important task for the development of large-scale practical quantum computers. Specifically, the development of proposals for quantum computation must ... -
Improved Diagnostics & Performance for Quantum Error Correction
(University of Waterloo, 2023-08-04)Building large scale quantum computers is one of the most exciting ventures being pursued by researchers in the 21st century. However, the presence of noise in quantum systems poses a major hindrance towards this ambitious ... -
Information flow at the quantum-classical boundary
(University of Waterloo, 2008-08-28)The theory of decoherence aims to explain how macroscopic quantum objects become effectively classical. Understanding this process could help in the search for the quantum theory underlying gravity, and suggest new schemes ... -
Modeling and managing noise in quantum error correction
(University of Waterloo, 2023-10-19)Simulating a quantum system to full accuracy is very costly and often impossible as we do not know the exact dynamics of a given system. In particular, the dynamics of measurement noise are not well understood. For this ... -
On single-crystal solid-state NMR based quantum information processing
(University of Waterloo, 2010-05-19)Quantum information processing devices promise to solve some problems more efficiently than their classical counterparts. The source of the speedup is the structure of quantum theory itself. In that sense, the physical ... -
Theory and Mitigation of Crosstalk on Quantum Information Processors
(University of Waterloo, 2023-09-08)Successfully implementing large-scale quantum computation has proven to be an exceptionally arduous task. Decoherence and imperfect control limit the coherent manipulation of large ensembles of particles. While quantum ...
