Entanglement as the cross-symmetric part of quantum discord
Chunhe Xiong, Sunho Kim, Asutosh Kumar +3
In this paper, we show that the minimal quantum discord over "cross-symmetric" state extensions is an entanglement monotone. In particular, we show that the minimal Bures distance…

Partial coherence versus entanglement
Sunho Kim, Chunhe Xiong, Shunlong Luo +2
We study partial coherence and its connections with entanglement. First, we provide a sufficient and necessary condition for bipartite pure state transformation under partial incoh…
