Carbon nanotube electromechanical systems: Non-linear dynamics and self-oscillation
(University of Waterloo, 2020-05-13)This thesis is motivated by the many sensing applications of carbon nanotube (CNT) nano-electromechanical systems (NEMS), both previous state-of-the-art demonstrations and proposed new uses. This research is particularly ... -
An experimental study of single hole spin qubit coherence in a GaAs/AlGaAs double quantum dot device
(University of Waterloo, 2024-01-15)This thesis discusses a series of experiments performed on a p-type laterally-gated GaAs/AlGaAs double quantum dot device. The main purpose of these experiments was to explore the potential of a theoretically-predicted ... -
Investigation of Photon Interactions with Semiconductor Quantum Dot Devices for Quantum Communication Applications
(University of Waterloo, 2020-01-21)A major goal in the field of quantum communication is to achieve long-distance (>100 km) transmission of quantum information, which would allow for the formation of a global quantum network. Devices called 'quantum repeaters' ... -
Quantum dot devices in silicon and dopant-free GaAs/AlGaAs heterostructures
(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 ... -
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 magnetic force sensing of single molecules using suspended carbon nanotubes
(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 ...
