Tighter entropic uncertainty relations in the presence of quantum memories for complete sets of mutually unbiased bases
Qing-Hua Zhang, Cong Xu, Jing-Feng Wu +1
Entropic uncertainty relations provide an information-theoretic framework for quantifying the fundamental indeterminacy inherent in quantum mechanics. We propose more stringent qua…
Schmidt number criterion via general symmetric informationally complete measurements
Zhen Wang, Bao-Zhi Sun, Shao-Ming Fei +1
The Schmidt number characterizes the quantum entanglement of a bipartite mixed state and plays a significant role in certifying entanglement of quantum states. We derive a Schmidt…
Coherence Concurrence for X States
Ming-Jing Zhao, Teng Ma, Zhen Wang +2
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 atta…
Trace distance measure of coherence for a class of qudit states
Zhen Wang, Yan-Ling Wang, Zhi-Xi Wang
Recently, trace distance measure of coherence has been proposed for characterizing the coherence of a given quantum state. However, it seems difficult to estimate the optimal incoh…
Generating multi-photon W-like states for perfect quantum teleportation and superdense coding
Ke Li, Fan-Zhen Kong, Ming Yang +3
An interesting aspect of multipartite entanglement is that for perfect teleportation and superdense coding, not the maximally entangled W states but a special class of non-maximall…
Monogamous property of generalized W states in three-qubit systems in terms of relative entropy of entanglement
Zhen Wang, Xiu-Hong Gao, Zhi-Xi Wang
Because of the difficulty in getting the analytic formula of relative entropy of entanglement, it becomes troublesome to study the monogamy relations of relative entropy of entangl…
