The effect of channel decoherence on entangled coherent states: A theoretical analysis
Yao Yao, Hong-Wei Li, Zhen-Qiang Yin +2
We analyse decoherence properties of entangled coherent states (ECSs) due to channel losses, and compare to the performance of bi-photon Bell states. By employing the concept of "e…

Geometric interpretation of the geometric discord
Yao Yao, Hong-Wei Li, Zhen-Qiang Yin +1
We investigate the level surfaces of geometric measure of quantum discord, and provide a pictorial interpretation of geometric discord for Bell-diagonal states. We have observed it…

Quantum discord of ensemble of quantum states
Yao Yao, Jing-Zheng Huang, Xu-Bo Zou +4
We highlight an information-theoretic meaning of quantum discord as the gap between the ac- cessible information and the Holevo bound in the framework of ensemble of quantum states…
