Quantum Information Science with Solid-State Spin Defects is an emerging and dynamic field that leverages optically interfaced solid-state spins for several quantum information applications. One example is the electron and nearby nuclear spins associated with nitrogen-vacancy centers in diamonds, which exhibit remarkable quantum coherence at room temperature and can be optically addressed. Over the past decades, these systems have shown promise as quantum registers for quantum computation and quantum networks. Additionally, they are competitive candidates for quantum sensors capable of characterizing electric and magnetic fields, pressure, and temperature at the nanoscale, thus pushing the boundaries in biology, material science, condensed matter physics, and geoscience. However, despite these advantages, various decoherence sources and experimental imperfections still hinder the realization of large-scale quantum information processing and practical quantum sensing.
This Research Topic aims to improve the performance of solid-state spin systems for multiple quantum information applications, including quantum sensing, quantum computing, quantum simulation, and quantum networks. The goal is to employ novel technologies to explore the potential of these systems further and enable new, exciting research. Specifically, the research will focus on advanced quantum and classical control techniques, such as quantum optimal control and machine learning, to enhance efficiency and robustness against various noises and imperfections.
Additionally, cutting-edge fabrication technologies, such as surface treatment and microfabricated cavities, will be investigated to reduce noise and enhance quantum coherent properties. Material engineering and the exploration of new defects will also be pursued to open more opportunities and overcome the limitations of existing systems, thereby expanding the field of applications.
