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,…
