Reply to "Comment on `Multiparty quantum mutual information: An alternative definition'"
Asutosh Kumar
We reaffirm the claim of Lee et al. [preceding Comment, Phys. Rev. A 108, 066401 (2023)] that the expression of quantum dual total correlation of a multipartite system in terms of…
Dilation, Discrimination and Uhlmann's Theorem of Link Products of Quantum Channels
Qiang Lei, Liuheng Cao, Asutosh Kumar +1
The study of quantum channels is the most fundamental theoretical problem in quantum information and quantum communication theory. The link product theory of quantum channels is an…
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…
