    • Characterizing Errors in Quantum Information Processors 

      Sanders, Yuval (University of Waterloo, 2016-05-12)
      Error-free computation is an unattainable ideal, yet our world now contains many computers that appear error-free to their users. That such things are possible is explained by sophisticated theorems that demonstrate the ...
    • Control techniques in spin based quantum computation 

      Katiyar, Hemant (University of Waterloo, 2019-07-11)
      Working on quantum systems entail different interests, for example, working on fundamental understanding of quantum systems also lay foundation for better quantum computation techniques. A test for whether a system is ...
    • The Effects of Quantum Error Correction on Noisy Systems 

      Beale, Stefanie Joyce (University of Waterloo, 2018-08-23)
      Full accuracy simulations of quantum systems are very costly, and as a result most studies of quantum error correction assume a probabilistic Pauli error model, largely because such errors can be e ciently simulated. ...
    • Exploring the foundation of quantum information in quantum optics 

      Ma, Xian (University of Waterloo, 2016-09-21)
      Quantum information is promising in solving certain computational problems and information security. The power of its speed up and privacy is based on one of the most tested physical theory: quantum mechanics. Many of ...
    • Indium Thin Films in Multilayer Superconducting Quantum Circuits 

      McRae, Corey Rae (University of Waterloo, 2018-01-03)
      The superconducting quantum computer is an implementation of the quantum computer and a current leader the field in terms of performance and potential for scalability to large systems. Its two main components are the ...
    • Modeling and managing noise in quantum error correction 

      Beale, Stefanie (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 ...
    • Near-Term Quantum Algorithms for Classical Sampling 

      Orfi, Alev (University of Waterloo, 2023-08-14)
      In the current era of noisy intermediate-scale quantum devices, quantum sampling algorithms have been of great interest as they permit errors in their execution while maintaining their advantage over classical counterparts ...
    • New methods in quantum error correction and fault-tolerant quantum computing 

      Chamberland, Christopher (University of Waterloo, 2018-10-22)
      Quantum computers have the potential to solve several interesting problems in polynomial time for which no polynomial time classical algorithms have been found. However, one of the major challenges in building quantum ...
    • Novel Heat-Bath Algorithmic Cooling methods 

      Rodríguez-Briones, Nayeli Azucena (University of Waterloo, 2020-08-20)
      The field of quantum information has inspired new methods for cooling physical systems at the quantum scale by manipulating entropy in an algorithmic way, such as heat-bath algorithmic cooling (HBAC). These methods not ...
    • Novel Methods in Quantum Error Correction 

      Jochym-O'Connor, Tomas Raphael (University of Waterloo, 2016-08-24)
      Quantum error correction is the backbone of fault-tolerant quantum computation, a necessary requirement for any large scale quantum computer. The fault-tolerance threshold theorem has long been a target for experimental ...
    • On the Power and Limitations of Shallow Quantum Circuits 

      Parham, Natalie (University of Waterloo, 2022-09-01)
      Constant-depth quantum circuits, or shallow quantum circuits, have been shown to exhibit behavior that is uniquely quantum. This thesis explores the power and limitations of constant-depth quantum circuits, in particular ...
    • Quantum Algorithms for Interpolation and Sampling 

      Motamedi, Arsalan (University of Waterloo, 2023-08-15)
      Gibbs sampling from continuous real-valued functions is a challenging problem of interest in machine learning. Here we leverage quantum Fourier transforms to build a quantum algorithm for this task when the function is ...
    • Quantum dot devices in silicon and dopant-free GaAs/AlGaAs heterostructures 

      Buonacorsi, Brandon (University of Waterloo, 2021-01-29)
      Single spin quantum dot qubits in silicon are a promising candidate for a scalable quantum processor due to their long coherence times, compact size, and ease of integration into existing fabrication technologies. Realizing ...
    • Representation, Characterization, and Mitigation of Noise in Quantum Processors 

      Lin, Junan (University of Waterloo, 2023-05-26)
      Quantum computers have the potential to outperform classical computers on several families of important problems, and have a great potential to revolutionize our understanding of computational models. However, the presence ...
    • Representing and Probing Errors in Quantum Information Processing Devices 

      Lin, Junan (University of Waterloo, 2018-08-24)
      The quality of quantum information processing devices has been improving at an unprecedented speed. How to faithfully represent the quality of these devices has become an increasingly imminent problem. In this thesis we ...
    • Towards simulating 2D effects in lattice gauge theories on a quantum computer 

      Paulson, Daniel (University of Waterloo, 2020-10-26)
      Quantum Field Theories (QFTs) are the most successful theories for describing nature at its most fundamental level. Despite the fact that QFTs are capable of predicting a wide range of phenomena, obtaining solutions to ...
    • Violation of an augmented set of Leggett-Garg inequalities and the implementation of a continuous in time velocity measurement 

      Majidy, Shayan-Shawn (University of Waterloo, 2019-07-11)
      Macroscopic realism (MR) is the view that a system may possess definite properties at any time independent of past or future measurements, and may be tested experimentally using the Leggett-Garg inequalities (LGIs). In ...
