Resource theories of quantum coherence is a very hot topic in quantum information of late. It seeks to capture our intuition of what it means it be quantum mechanical in single systems. This work, lead by Ma Jiajun, a third year PhD student in the group, managed to to connect coherence of quantum discord - a measure of quantumness on bipartite systems. The basic idea is coherence is discord are closely connect. The former can be used as a resource to create the latter.
