    • Achievable Polarization for Heat-Bath Algorithmic Cooling 

      Rodríguez Briones, Nayeli Azucena (University of Waterloo, 2015-08-17)
      Highly pure quantum states play a central role in applications of quantum information science, both as initial states for quantum algorithms and as resources for quantum error correction. Controlled preparation of pure ...
    • Characterization, Verification and Control for Large Quantum Systems 

      Granade, Christopher E. (University of Waterloo, 2015-03-31)
      Quantum information processing offers potential improvements to a wide range of computing endevaors, including cryptography, chemistry simulations and machine learning. The development of practical quantum information ...
    • Coherent control of nuclear and electron spins for quantum information processing 

      Park, Kyungdeock (University of Waterloo, 2015-08-10)
      The ability to perform quantum error correction (QEC) arbitrarily many cycles is a significant challenge for scalable quantum information processing (QIP). Key requirements for multiple-round QEC are a high degree of quantum ...
    • Experimental Investigation into Spatial Quantum Optical Properties for Satellite Targeting through the Turbulent Atmosphere 

      Pugh, Christopher (University of Waterloo, 2013-09-04)
      A major field of research at the current time is that of implementing Quantum Key Distribution over large distances using satellites. If this protocol works with this technology, it will have huge implications on future ...
    • Experimentally Testable Noncontextuality Inequalities Via Fourier-Motzkin Elimination 

      Krishna, Anirudh (University of Waterloo, 2015-09-29)
      Generalized noncontextuality as defined by Spekkens is an attempt to make precise the distinction between classical and quantum theories. It is a restriction on models used to reproduce the predictions of quantum mechanics. ...
    • Initialization and characterization of open quantum systems 

      Wood, Christopher J. (University of Waterloo, 2015-08-21)
      In this thesis we address three topics of open quantum systems theory. The first concerns the operational characterization of an open quantum system. We develop a graphical calculus for open quantum systems and use it to ...
    • Mode Invisibility Technique - A Quantum Non-Demolition Measurement for Light 

      Onuma-Kalu, Marvellous (University of Waterloo, 2014-07-14)
      The act of measuring an observable of a quantum system introduces backaction noise to the measured system. In the most extreme case, the system gets destroyed with its state left unavailable for future measurement. An ...
    • Parallelizing quantum circuit synthesis 

      Di Matteo, Olivia (University of Waterloo, 2015-04-24)
      We present an algorithmic framework for parallel quantum circuit synthesis using meet-in-the-middle synthesis techniques. We also present two implementations thereof, using both threaded and hybrid parallelization ...
    • Practical Quantum Communication 

      Arrazola, Juan Miguel (University of Waterloo, 2015-10-30)
      Current communication networks are based on classical physics and classical information-processing. However, for nearly a century, we have known that at its most fundamental level, the universe is governed by the laws of ...
    • The Practical Realization of Quantum Repeaters: An Exploration 

      Luong, David (University of Waterloo, 2015-10-27)
      This thesis is an exploration of quantum repeaters from a practical point of view. Quantum repeaters are devices which help improve the quantum communication capacity of a lossy bosonic channel (which include photonic ...
    • Quantum tests of causal structures and non-orthogonal states 

      Agnew, Megan (University of Waterloo, 2014-06-13)
      This thesis details two experimental tests that can be applied to particular quantum states to reveal important information. We begin by discussing the relevant background in quantum information. We introduce qubits and ...
    • The Security of Simplified Trusted Relays 

      Stacey, William (University of Waterloo, 2014-08-27)
      This thesis examines the security of performing quantum key distribution (QKD) with a simplified trusted relay (STR). The protocol carries out the quantum phase of a conventional trusted relay, however, reduces the required ...
    • Theoretical Analysis of A Protected Superconducting Qubit 

      Shen, Feiruo (University of Waterloo, 2015-11-02)
      In the past few decades, quantum computation has become an active area of research due to prospects to execute high-efficiency quantum algorithms. Quantum algorithms promise to accelerate many practical computation problems, ...
    • Topics on the information theoretic limits of quantum information processing and its implementation 

      Raeisi, Sadegh (University of Waterloo, 2015-02-24)
      Recent advances in quantum technologies enabled us to make large quantum states and pushed towards examining quantum theory at the macroscopic level. However observation of quantum e ects at a macroscopic level still ...
    • Towards magnetic force sensing of single molecules using suspended carbon nanotubes 

      Willick, Kyle (University of Waterloo, 2014-08-19)
      Measuring the magnetic moment of a single spin remains an experimental challenge. Measuring such a moment at timescales relevant to relaxation in many small spin systems, even more so. However, such a measurement would ...
