Liang Jiang


Jiang's research focuses on spin physics, topological phases, and quantum technology. The first research direction is about the diamond, in particular the spin coherence properties associated with the diamond color centers, which can be used to build nano-magnetometer and store quantum information. The second direction investigates quantum systems with topological order, which is a fundamentally new type of order beyond Landau symmetry-breaking description and can be used to encode quantum information robust against local perturbations. The third direction is quantum networks, in particular quantum communication over long distances, which will be robust against various imperfections and provide unconditional security.
