Coherence Concurrence for X States [PDF]
Quantum Inf Process 19, 104 (2020), 2020 We study the properties of coherence concurrence and present a physical explanation analogous to the coherence of assistance. We give an optimal pure state decomposition which attains the coherence concurrence for qubit states. We prove the additivity of coherence concurrence under direct sum operations in another way. Using these results, we calculate

Negativity and Concurrence of mixed 2X2 states [PDF]
arXiv, 2000 We consider two measures of entanglement of mixed bipartite states of dimension 2X2: concurrence and negativity. We first prove the conjecture of Eisert and Plenio that concurrence can never be smaller than negativity. We then characterise all states for which concurrence equals negativity and also those states for which the difference between ...

Universal complementarity between coherence and intrinsic concurrence for two-qubit states
New Journal of Physics, 2019 Entanglement and coherence are two essential quantum resources for quantum information processing. A natural question arises of whether there is a direct link between them.

Concurrence Measurement for the Two-Qubit Optical and Atomic States
Entropy, 2015 Concurrence provides us an effective approach to quantify entanglement, which is quite important in quantum information processing applications. In the paper, we mainly review some direct concurrence measurement protocols of the two-qubit optical or ...

Concurrence Percolation in Quantum Networks. [PDF]
Physical Review Letters, 2021 Establishing long-distance quantum entanglement, i.e., entanglement transmission, in quantum networks (QN) is a key and timely challenge for developing efficient quantum communication.

Coherence, path predictability, and I concurrence: A triality [PDF]
Physical Review A, 2021 It is well known that fringe contrast is not a good quantifier of the wave nature of a quanton in multipath interference. A new interference visibility, based on the Hilbert-Schmidt coherence is introduced.

Concurrence percolation threshold of large-scale quantum networks
Communications Physics, 2022 Quantum networks describe communication networks that are based on quantum entanglement. A concurrence percolation theory has been recently developed to determine the required entanglement to enable communication between two distant stations in an ...

The concurrence of DNA methylation and demethylation is associated with transcription regulation
Nature Communications, 2021 The mammalian DNA methylome is formed by two antagonizing processes, methylation by DNA methyltransferases (DNMT) and demethylation by ten-eleven translocation (TET) dioxygenases.

Case Report: The First Reported Concurrence of Wilson Disease and Bilateral Retinitis Pigmentosa
Frontiers in Medicine, 2022 BackgroundWilson disease (WD) and retinitis pigmentosa (RP) are common genetic disorders in clinical practice, however, the concurrence of WD and RP has never been reported before.
