As the need for secure communication grows in a globally connected world, quantum computing offers a promising pathway to groundbreaking security technologies through quantum bits or qubits. A qubit, unlike a traditional computer bit, can exist in multiple states simultaneously, enabling exceptional computational power for complex tasks such as encrypted communication and advanced simulations. To achieve qubits on an atomic scale, precise material engineering is essential. This project aims to develop and control specific atomic-scale defects in two-dimensional (2D) transition metal dichalcogenides (TMDs), creating an innovative foundation for qubit-based systems. Leveraging proton irradiation, the research will systematically generate and control defects like antisites in materials such as tungsten disulfide (WS2) and tungsten diselenide (WSe2), critical for scalable and stable qubit operation. Through an integrated approach that combines computational modeling and experimental characterization, this project seeks to decode the physics behind defects and establish methods to manipulate these defects without introducing strain or foreign elements, paving the way for qubits that operate at room temperature and are robust enough for practical applications.
