Interfacing quantum systems.

We study how quantum systems behave and evolve in real-world environments. By precisely controlling quantum degrees of freedom (e.g., spins and phonons), we develop innovative approaches to interface quantum systems to other scientific domains.

Qian Ling and Zak visit from the University of Cambridge!

A big welcome to Qian Ling and Zak who dropped by the lab from Cambridge! Qian Ling (from the QOMS group at Cavendish Laboratory) gave an awesome talk on her scanning NV microscopy research, and Zak (from QEG) joined the tour to check out our setup. Thanks for dropping by! Great science chats, great company! ☕️✨

Our first NV ODMR signal!

A Friday milestone for the lab! On 4 September, we observed our first optically detected magnetic resonance (ODMR) signal from an NV centre in diamond. As the applied magnetic field increased, the resonance peaks split further apart—an exciting first step for our diamond quantum-sensing work! 💎✨

People

QSE Lab welcomes its first students

Dayne Dai and Huaizheng Ye join as PhD students supported by NUS Research Scholarships, leading our NV-in-diamond and quantum Brillouin efforts, respectively. Grace Lee, Yong Le Lee, Surya Nayar, Qi Yuan Yu, Kristoffer Videl Wijono, Aliyev, Khadijah and Vivekan will contribute across the lab’s research through year-long undergraduate projects.
