Relative Quantum Resource Theory and Operational Applications in Subchannel Discrimination
Sunho Kim, Chunhe Xiong, Junde Wu
A central problem in quantum resource theory is to give operational meaning to quantum resources that can provide clear advantages in certain physical tasks compared to the convex…
Quantifying dynamical coherence with coherence measures
Sunho Kim, Chunhe Xiong, Asutosh Kumar +2
Quantum coherence, like entanglement, is a fundamental resource in quantum information. In recent years, remarkable progress has been made in formulating resource theory of coheren…
Converting coherence based on positive-operator-valued measures into entanglement
Sunho Kim, Chunhe Xiong, Asutosh Kumar +1
Quantum resource theories provide a diverse and powerful framework for extensively studying the phenomena in quantum physics. Quantum coherence, a quantum resource, is the basic in…
Partial coherence and quantum correlation with fidelity and affinity distances
Chunhe Xiong, Asutosh Kumar, Minyi Huang +3
A fundamental task in any physical theory is to quantify certain physical quantity in a meaningful way. In this paper we show that both fidelity distance and affinity distance sati…
Family of coherence measures and duality between quantum coherence and path distinguishability
Chunhe Xiong, Asutosh Kumar, Junde Wu
Coherence measures and their operational interpretations lay the cornerstone of coherence theory. In this paper, we introduce a class of coherence measures with -affinity, say $…
