On the optimal measurement for quantum discord of two-qubit states
Mingjun Shi, Chunxiao Sun, Fengjian Jiang +2
We present an efficient method to solve the quantum discord of two-qubit X states exactly. A geometric picture is used to clarify whether and when the general POVM measurement is s…

Geometric picture of quantum discord for two-qubit quantum states
Mingjun Shi, Fengjian Jiang, Chunxiao Sun +1
Among various definitions of quantum correlations, quantum discord has attracted considerable attention. To find analytical expression of quantum discord is an intractable task. Ex…
