This lecture introduces the fundamental principles and applications of quantum sensing based on solid-state defect qubits, with a focus on systems such as nitrogen-vacancy (NV) centers in diamond. It covers the quantum mechanical description of spin states, optical initialization and readout, and the interaction of defect spins with external fields. Particular emphasis is placed on understanding coherence, decoherence mechanisms, and their impact on sensing performance.
The module follows a project-based, hands-on learning approach that combines theoretical lectures with practical applications. Students will first build core knowledge and then apply it in a small research-oriented project, fostering creativity, problem-solving skills, and critical thinking. In addition to fundamental concepts, the course introduces first-principles computational approaches (e.g., density functional theory) for modeling quantum materials and their properties. The grading is performed based on the presentation of their projects and the oral exam.
