The emerging field of quantum information science promises to transform a diverse range of scientific fields, ranging from computation to sensing and metrology. The interdisciplinary scientific community laid the groundwork for the next generation of quantum technologies through key advances in understanding the fundamental unit of quantum information science, the qubit. Electronic spin is a promising platform for qubits, demonstrating suitably long coherence times, optical initialization, and single spin addressability. Herein, we discuss recent accomplishments and future progress from our group targeted at imbuing transition metal complexes with the aforementioned properties, creating a pathway to fusing spatial precision with long coherence times. A strong emphasis of this feature article is progressing towards single spin measurements via a chemical approach for imbuing molecular qubits with an optically-induced spin polarization mechanism.
新兴的量子信息科学领域有望彻底改变从计算到传感和计量等各种科学领域。通过在理解量子信息科学的基本单位——qubit 方面取得关键进展，跨学科的科学界为下一代量子技术奠定了基础。电子自旋是量子比特的一个很有前途的平台，具有合适的长相干时间、光学初始化和单自旋可寻址性。在这里，我们讨论了我们小组的最新成果和未来进展，旨在赋予过渡金属配合物上述特性，为融合空间精度和长相干时间开辟一条途径。本文的一个重点是通过一种化学方法来实现单自旋测量，该方法通过光学诱导的自旋极化机制赋予分子量子比特自旋极化。
