Uncertainty conservation relations: theory and experiment
Hengyan Wang, Zhihao Ma, Shengjun Wu +8
As a very fundamental principle in quantum physics, uncertainty principle has been studied intensively via various uncertainty inequalities. Based on the information measure introd…
Coherence generating power of unitary transformations via probabilistic average
Lin Zhang, Zhihao Ma, Zhihua Chen +1
We study the ability of a quantum channel to generate quantum coherence when it applies to incoherent states. Based on probabilistic averages, we define a measure of such coherence…
Activation of entanglement from quantum coherence and superposition
Lu-Feng Qiao, Jun Gao, Alexander Streltsov +11
Quantum entanglement and coherence are two fundamental features of nature, arising from the superposition principle of quantum mechanics. While considered as puzzling phenomena in…
Operational one-to-one mapping between coherence and entanglement measures
Huangjun Zhu, Zhihao Ma, Zhu Cao +2
We establish a general operational one-to-one mapping between coherence measures and entanglement measures: Any entanglement measure of bipartite pure states is the minimum of a su…
Experimental Test of Relation between Coherence and Path Information
Jun Gao, Zhi-Qiang Jiao, Chen-Qiu Hu +6
Quantum coherence stemming from the superposition behaviour of a particle beyond the classical realm, serves as one of the most fundamental features in quantum mechanics. The wave-…
Sharp Continuity Bounds for Entropy and Conditional Entropy
Zhihua Chen, Zhihao Ma, Ismail Nikoufar +1
The Renyi entropy plays an essential role in quantum information theory. We study the continuity estimation of the Renyi entropy. An inequality relating the Renyi entropy differenc…
