Towards the standardization of quantum state verification using optimal strategies
Xinhe Jiang, Kun Wang, Kaiyi Qian +7
Quantum devices for generating entangled states have been extensively studied and widely used. As so, it becomes necessary to verify that these devices truly work reliably and effi…
Entanglement Detection via Direct-Sum Majorization Uncertainty Relations
Kun Wang, Nan Wu, Fangmin Song
In this paper we investigate the relationship between direct-sum majorization formulation of uncertainty relations and entanglement, for the case of two and many observables. Our p…
Uncertainty Relations in the Presence of Quantum Memory for Mutually Unbiased Measurements
Kun Wang, Nan Wu, Fangmin Song
In [Berta 2014 Entanglement], uncertainty relations in the presence of quantum memory was formulated for mutually unbiased bases using conditional collision entropy. In this paper,…
The Lackadaisical Quantum Walker is NOT Lazy at all
Kun Wang, Nan Wu, Ping Xu +1
In this paper, we study the properties of lackadaisical quantum walks on a line. This model is first proposed in~\cite{wong2015grover} as a quantum analogue of lazy random walks wh…
