Monogamy of quantum discord
Yu Guo, Lizhong Huang, Yang Zhang
The original quantum discord (QD) is shown to be not monogamous except for the three-qubit states. Recently, a complete monogamy relation for multiparty quantum system was establis…
Long-distance entanglement purification for quantum communication
Xiao-Min Hu, Cen-Xiao Huang, Yu-Bo Sheng +8
High-quality long-distance entanglement is essential for both quantum communication and scalable quantum networks. Entanglement purification is to distill high-quality entanglement…
Nonlocality, steering and quantum state tomography in a single experiment
Chang-Jiang Huang, Guo-Yong Xiang, Yu Guo +5
We investigate whether paradigmatic measurements for quantum state tomography, namely mutually unbiased bases and symmetric informationally complete measurements, can be employed t…
Pathways for entanglement based quantum communication in the face of high noise
Xiao-Min Hu, Chao Zhang, Yu Guo +10
Entanglement based quantum communication offers an increased level of security in practical secret shared key distribution. One of the fundamental principles enabling this security…
Multipartite Entanglement Measure and Complete Monogamy Relation
Yu Guo, Lin Zhang
Although many different entanglement measures have been proposed so far, much less is known in the multipartite case, which leads to the previous monogamy relations in literatures…
Advances in quantum dense coding
Yu Guo, Bi-Heng Liu, Chuan-Feng Li +1
Quantum dense coding is one of the most important protocols in quantum communication. It derives from the idea of using quantum resources to boost the communication capacity and no…
