Duistermaat-Heckman measure and the mixture of quantum states
Lin Zhang, Yixin Jiang, Junde Wu
In this paper, we present a general framework to solve a fundamental problem in Random Matrix Theory (RMT), i.e., the problem of describing the joint distribution of eigenvalues of…
Simulating broken -symmetric Hamiltonian systems by weak measurement
Minyi Huang, Ray-Kuang Lee, Lijian Zhang +2
By embedding a -symmetric (pseudo-Hermitian) system into a large Hermitian one, we disclose the relations between -symmetric Hamiltonians and weak measurement th…
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…
Protocol for unambiguous quantum state discrimination using quantum coherence
Sunho Kim, Longsuo Li, Asutosh Kumar +5
Roa et al. showed that quantum state discrimination between two nonorthogonal quantum states does not require quantum entanglement but quantum dissonance only. We find that quantum…
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 $…
