| Title | Expanding Horizons in Quantum Photonics: Single-Photon Emitters in Two-Dimensional Materials |
| Summary | In the rapidly advancing field of quantum technologies, single-photon emitters (SPEs) are crucial for applications in quantum computing, secure communications, and high-precision sensing. Prominently, materials with wide bandgaps, like diamond and silicon carbide, are excellent platforms for these emitters due to their superior optical qualities and the ability to maintain stable quantum outputs at room temperature. This makes them reliable and effective for quantum operations. Despite the strengths of diamond and silicon carbide, exploring van der Waals materials opens up exciting opportunities. These materials facilitate the incorporation of SPEs into two-dimensional (2D) quantum devices, enhancing their adaptability for photonic applications. Van der Waals materials also provide greater ease of fabrication, better compatibility with other components, and are more cost-effective. This project aims to deepen our understanding of 2D-based SPEs by exploring their potential. Given the extensive diversity within the 2D materials family, we seek to harness this variety to discover SPEs with novel properties and enhanced performance metrics. The core of our investigation focuses on the optical characteristics of these SPEs, assessing how they can be precisely tuned using strain and electric fields to optimize their functionality. Through rigorous fabrication and characterization processes, our goal is to expand the spectrum of available emission energies, enhance thermal stability, and refine the linewidth of these emitters to make them more suitable for quantum photonic applications. Such advancements are expected to push the boundaries of current technology, offering more versatile and robust components for quantum computing and secure communication systems. Moreover, this project provides a practical training ground for students, who will gain invaluable hands-on experience in preparing strain-engineered 2D material samples. Students will engage in pivotal experiments designed to validate and refine SPE properties, thereby providing insights into their operational dynamics and potential for real-world applications. |
