Super quantum discord for X-type states
Tao Li, Teng Ma, Yaokun Wang +2
Weak measurement is a new way to manipulate and control quantum systems. Different from projection measurement, weak measurement only makes a small change in status. Applying weak…
Towards Grothendieck Constants and LHV Models in Quantum Mechanics
Bobo Hua, Ming Li, Tinggui Zhang +3
We adopt a continuous model to estimate the Grothendieck constants. An analytical formula to compute the lower bounds of Grothendieck constants has been explicitly derived for arbi…
A Note on Mutually Unbiased Unextendible Maximally Entangled Bases in
Halqem Nizamidin, Teng Ma, Shao-Ming Fei
We systematically study the construction of mutually unbiased bases in , such that all the bases are unextendible maximally entangled ones.…
Maximal Holevo quantity based on weak measurements
Yao-Kun Wang, Shao-Ming Fei, Zhi-Xi Wang +2
The Holevo bound is a keystone in many applications of quantum information theory. We propose "weak maximal Holevo quantity" with weak measurements as the generalization of the sta…
