个人简介

张志强,2019年在新加坡国立大学荣获博士学位,主要从事基于腔量子电动力学的量子模拟和量子信息实研究。在2019年至2023年间,在新加坡国立大学担任高级博士后研究员,专注于钡离子和镥离子的光钟系统研究。20241月加入了量子物理和量子信息研究部,目前的研究方向主要集中在镥离子和镱离子的超高精度光钟系统,涵盖离子阱、单离子光钟、多离子光钟、可搬运光钟、空间光钟以及芯片光钟等领域。

近年主要学术成果包括:成功地实现了Dicke模型的量子模拟,并首次观测到超震荡辐射量子相变;国际上首次在实验上论证多离子光钟的可行性;首次在实验中建立镥离子光钟并实现镥离子光钟的比对:该光钟的误差每百亿年不超过1秒,截至20243月,仍保持原子钟准确度最高记录,离子光钟比对结果最佳记录。迄今,在science advancesPRL, Optica等学术期刊发表论文10余篇。
