Non-commutativity measure of quantum discord
Yu Guo
Quantum discord is a manifestation of quantum correlations due to non-commutativity rather than entanglement. Two measures of quantum discord by the amount of non-commutativity via…
Quantum correlation induced by the average distance between the reduced states
Yu Guo, Xiulan Li, Bo Li +1
A new quantum correlation in terms of the average distance between the reduced state and the -th output reduced states under local von Neumann measurements is proposed. It is sh…
Quantum correlation exists in any non-product state
Yu Guo, Shengjun Wu
Simultaneous existence of correlation in complementary bases is a fundamental feature of quantum correlation, and we show that this characteristic is present in any non-product bip…
Unextendible entangled bases with fixed Schmidt number
Yu Guo, Shengjun Wu
The unextendible product basis (UPB) is generalized to the unextendible entangled basis with any arbitrarily given Schmidt number (UEBk) for any bipartite system $\mathbb{C}^d\…
