Towards InAs nanowire double quantum dots for quantum information processing
(University of Waterloo, 2010-11-03)Currently, a major challenge for solid-state spin qubit systems is achieving one-qubit operations on a timescale shorter than the spin coherence time, T2*, a goal currently two orders of magnitude away. By taking advantage ... -
Towards Practical Hybrid Quantum / Classical Computing
(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 ... -
Towards simulating 2D effects in lattice gauge theories on a quantum computer
(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 ... -
Tunable Coupler in Superconducting Circuits and Impedance Engineering for Josephson Parametric Amplifier
(University of Waterloo, 2020-09-04)In this thesis, we study two topics on superconducting circuits. The first topic is the tunable coupler for resonators. This coupler is implemented with a superconducting circuit coupling with resonators in the dispersive ... -
Ultra-Cold CsLi Molecules as a Platform for Quantum Information Processing
(University of Waterloo, 2022-12-19)Despite their proposal 40 years ago, quantum computers are still in their infancy, with a panoply of various systems demonstrated as potential methods of quantum information processing. Rydberg atoms are a leading platform, ... -
Universal Control in 1e-2n Spin System Utilizing Anisotropic Hyperfine Interactions
(University of Waterloo, 2010-09-30)ESR quantum computing presents faster means to perform gates on nuclear spins than the traditional NMR methods. This means ESR is a test-bed that can potentially be useful in ways that are not possible with NMR. The first ... -
Vacuum and Optical Designs for an Open-access Trapped Ion Quantum Processor

Variational Quantum Eigensolvers Applied to Problems in High Energy Physics
(University of Waterloo, 2021-01-13)Variational methods have long been used to study strongly-correlated quantum systems. Despite the successes of classical protocols, these are limited in the study of quantum systems, either due to numerical errors like the ... -
A walk through quantum noise: a study of error signatures and characterization methods
(University of Waterloo, 2019-09-17)The construction of large scale quantum computing devices might be one of the most exciting and promising endeavors of the 21st century, but it also comes with many challenges. As quantum computers are supplemented with ... -
WKB Analysis of Tunnel Coupling in a Simple Model of a Double Quantum Dot
(University of Waterloo, 2008-12-16)A simplified model of a double quantum dot is presented and analyzed, with applications to spin-qubit quantum computation. The ability to trap single electrons in semiconductor nanostructures has led to the proposal of ...
