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.

Prof. Jiang received his BS from Caltech in 2004 and PhD from Harvard University in 2009. He then worked as a Sherman Fairchild postdoctoral fellow at Caltech. In 2012, Jiang joined the faculty of Yale University as an assistant professor and later as an associate professor of Applied Physics. He was awarded the Alfred P. Sloan Research Fellowship, and the David and Lucile Packard Foundation Fellowship in 2013. In 2019, Jiang moved to his current position as professor at the University of Chicago Pritzker School of Molecular Engineering.

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.
