Quantum contextuality is a fundamental concept in quantum mechanics that has significant implications for modern quantum information science. It is the origin of quantum nonlocality, various nonclassical paradoxes, and a resource for many quantum information processing tasks and universal quantum computing. In recent years, experimental research on contextuality has progressed from theoretical studies to direct experimental tests. However, most experimental research has focused on specific predictions of contextuality, while other forms of contextuality and its practical applications in quantum information science are rarely explored. This thesis aims to bridge this gap by constructing and testing stronger forms of contextuality, exploring the connections between contextuality and other concepts in quantum information science, and demonstrating the application of contextuality in broader scenarios. The thesis discusses the relationship between quantum contextuality and nonlocality, the "all-versus-nothing" paradoxes from quantum contextuality, the ore- and post-selection paradoxes from quantum contextuality, and the topological protection of contextuality. It also presents experimental results that demonstrate the practical applications of contextuality in quantum communication, quantum cryptography, and quantum metrology. Overall, the thesis contributes to the understanding and development of quantum contextuality and its potential applications in quantum information science.
