Entanglement detection using mutually unbiased measurements
Bin Chen, Teng Ma, Shao-Ming Fei · Physical Review A · 2014
We study entanglement detection by using mutually unbiased measurements and provide a quantum separability criterion that can be experimentally implemented for arbitrary $d$-dimensional bipartite systems. We show that this criterion is more effective than the criterion based on mutually unbiased bases. For isotropic states our criterion becomes both necessary and sufficient.
