Family of Quantum Mutual Information in Multiparty Quantum Systems

Asutosh Kumar

The characterization of information within a multiparty system is both significant and complex. This paper presents the concept of generalized conditional mutual information, along…

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…

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…
