Overview of Academic Research

I primarily focus on quantum sensing and quantum communication research. I have developed cryogenic scanning single-spin magnetometry, applying it to solid materials and, for the first time, observing magnetic moiré patterns in twisted 2D magnetic materials. I've also established independent entangled-source interference technology, enabling quantum teleportation in a metropolitan fiber network. My work has been published in Science, Nature Photonics, PRL, etc.

Research Directions/Fields:

Diamond NV center quantum sensing and applications

Solid-state color center quantum relays
