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…

Interrelation between Partial Coherence and Quantum Correlations
Sunho Kim, Longsuo Li, Asutosh Kumar +1
Both coherence and entanglement stem from the superposition principle, capture quantumness of a physical system, and play a central role in quantum physics. In a multipartite quant…

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 $…
