1H MAS NMR Study of Water on Pd-MCM-41
(University of Waterloo, 2015-06-18)Hydrogen spillover represents one of the most promising avenues to achieve hydrogen storage at the density required for transportation applications. The spillover phenomenon, however, is a topic of much debate, with many ... -
Above Bandgap Hyperpolarization Mechanism in Isotopically Purified Silicon and Optimal Bayesian Experiment Design for $T_1$ Estimation
(University of Waterloo, 2018-05-24)This thesis is concerned with the mechanism underlying the above bandgap illumination Dynamic Nuclear Polarization (DNP) of phosphorus donors in isotopically purified silicon-28. Two proposed DNP models are introduced and ... -
Characterization and Control in Large Hilbert spaces.
(University of Waterloo, 2008-12-03)Computational devices built on and exploiting quantum phenomena have the potential to revolutionize our understanding of computational complexity by being able to solve certain problems faster than the best known classical ... -
Coherent control of nuclear and electron spins for quantum information processing
(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 ... -
¹H MAS NMR Spectral Coalescence of Water and Hydroxyl Resonances in MCM-41
(University of Waterloo, 2011-09-01)Solid state ¹H MAS NMR spectroscopy was used to investigate the temperature and hydration dependance of water and hydroxyl proton spectra of hydrated mesoporous MCM-41. The NMR spectra show a complex peak structure, with ... -
NMR STUDY OF EXCHANGE AND HYDRATION SITE IDENTIFICATION IN MCM-41
(University of Waterloo, 2007-01-16)Deuteron 1D and 2D NMR spectroscopy was used to study the dynamics of water molecules within the mesoporous material MCM-41. The deuteron spectra show three magnetization components for a sample hydrated to a 0.2 monolayer ... -
On Experimental Deterministic Quantum Computation with One Quantum Bit (DQC1)
(University of Waterloo, 2012-03-27)Quantum information processors have the ability to drastically change our world. By manipulating bits of information ruled by the laws of quantum mechanics, computational devices can perform some computations that are ... -
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 ... -
Origin of NMR Spectral Features in MCM-41 at Low Hydrations
(University of Waterloo, 2010-09-01)Although extensive literature exists on NMR of water in MCM-41, the origin of a number of NMR spectral features in this material had not been understood. Specifically, the OH proton resonance observed in the dry material ...
