The electron in Paul trap system has been recently proposed as a candidate for qubits in quantum information processing. In such a system, floating electrons are confined in vacuum using oscillating electric fields. Feasibility studies and experimental trapping at room temperature have shown that electrons satisfy all DiVincenzo's criteria, a common standard used to determine whether a system can be a good candidate to perform quantum computation. More importantly, electrons have several advantages in quantum information processing as compared to trapped ions. Electrons are spin-½...

Long-term frequency stability of silicon MEMS resonators is fundamentally limited by surface-driven degradation mechanisms, including corrosion, moisture adsorption, surface oxidation, and defect evolution. These processes progressively alter surface energy, mass, stiffness, and internal stress, leading to frequency drift, Q degradation, and reduced device lifetime. This work presents a corrosion-resistant encapsulation strategy that conformally coats silicon resonator surfaces with a chemically robust, high-hardness barrier layer engineered for long-term environmental stability. The...

Accurate and real-time gas detection is crucial for applications ranging from environmental monitoring to industrial processes. Traditional methods are often limited by low accuracy, slow response times, and high costs. This project introduces a scalable machine learning fusion system that integrates sensor fusion techniques to enhance detection performance. With encoder-decoder architectures and a decision fusion model, our approach significantly improves the accuracy of carbon dioxide sensing, achieving a mean absolute percentage error (MAPE) of 2.97% while reducing response and recovery...

3D printing offers unprecedented control over the design and fabrication of functional materials with complex architectures. In this project, we focus on developing textured ceramic structures using advanced 3D printing techniques. By engineering the resin formulation and printing process, we aim to align ceramic grains along designed orientations, enabling anisotropic properties tailored for transducer applications. The study will reveal the processing–structure–property correlations of textured ceramics, demonstrating how controlled grain orientation alignment and microstructural...
