Jiang Group

test

The Jiang Group investigates quantum control and quantum error correction to protect quantum information from decoherence for various physical platforms, with potential applications for quantum sensing, quantum transduction, quantum communication, and quantum computation.

The Jiang Group is recruiting graduate students and postdoctoral scholars.

Current Research

Liang Jiang theoretically investigates quantum systems and explores various quantum applications, such as quantum sensing, quantum transduction, quantum communication, and quantum computation. His research focuses on using quantum control and error correction to protect quantum information from decoherence to realize robust quantum information processing. He has worked on modular quantum computation, global-scale quantum networks, room-temperature nano-magnetometer, sub-wavelength imaging, micro-optical quantum transduction, and error-correction-assisted quantum sensing and simulation.
