Abstract Quantum coherence and quantum correlations are important resources for computation information. In this paper, using entropy-based measures, we investigate the relationships between correlated coherence, which is subsystems, two main kinds of as defined by discord well entanglement. particular, show that entanglement can be characterized coherence. Moreover, prove measure formulated lower upper bounded relative entropy formation, respectively, equal to all maximally states.
Quantum coherence plays a major role in the promotion for quantum information processing and designing technology. Since is rooted superposition principle, it vital to understand change with respect superpositions. Here we study bounds of superpositions high dimension. We consider three most frequently used measures coherence, i.e. relative entropy l 1 norm robustness coherence. For state (an arbitrary dimension) its decomposition, give upper lower terms states being superposed.
Quantum coherence is important in quantum mechanics, and its essence from superposition principle. We study the of any two pure states that their arbitrary superposition, obtain relationship between them. In case have support on orthogonal subspaces, simple, is, difference state average them smaller than 1. other cases, we different a little more complicated relationships. Furthermore, also lower bound superpositions.
The Schmidt number is an entanglement measure whose logarithm quantifies the zero-error cost of generating a given quantum state using local operations and classical communication. In this paper, we show that highly nonmultiplicative in sense for any integer n, there exist states remains constant when taking n copies state. These also provide rare instance which regularized can be computed exactly. We then explore question increasing by operations. describe class bipartite preserve pure...
Quantum coherence as an important quantum resource plays a key role in theory. In this paper, using entropy-based measures, we investigate the relations between correlated coherence, which is subsystems [K. C. Tan, H. Kwon, Y. Park, and Jeong, Phys. Rev. A 94, 022329 (2016)], two main kinds of correlations defined by discord well entanglement. particular, show that entanglement can be characterized coherence. Moreover, prove measure formulated lower upper bounded relative entropy formation,...
