The past century has witnessed the flourishing of organic radical chemistry. Stable organic radicals are highly valuable for quantum technologies thanks to their inherent room temperature quantum coherence, atomic-level designability, and fine tunability. In this comprehensive review, we highlight the potential of stable organic radicals as high-temperature qubits and explore their applications in quantum information science, which remain largely underexplored. Firstly, we summarize known spin dynamic properties of stable organic radicals and examine factors that influence their electron spin relaxation and decoherence times. This examination reveals their design principles and optimal operating conditions. We further discuss their integration in solid-state materials and surface structures, and present their state-of-the-art applications in quantum computing, quantum memory, and quantum sensing. Finally, we analyze the primary challenges associated with stable organic radical qubits and provide tentative insights to future research directions.
过去一个世纪见证了有机自由基化学的蓬勃发展。稳定的有机自由基因其固有的室温量子相干性、原子级可设计性和精细可调性，在量子技术中具有极高的价值。在这篇全面的综述中，我们强调了稳定有机自由基作为高温量子比特的潜力，并探讨了它们在量子信息科学中的应用，而这在很大程度上仍未得到充分探索。首先，我们总结了稳定有机自由基已知的自旋动力学特性，并研究了影响其电子自旋弛豫和退相干时间的因素。这项研究揭示了它们的设计原则和最佳操作条件。我们进一步讨论了它们在固态材料和表面结构中的集成，并展示了它们在量子计算、量子存储和量子传感方面的最新应用。最后，我们分析了与稳定有机自由基量子比特相关的主要挑战，并对未来的研究方向提供了初步见解。
