Construction of quantum states with special properties by projection methods
Xuefeng Duan, Chi-Kwong Li, Diane Christine Pelejo
We use projection methods to construct (global) quantum states with prescribed reduced (marginal) states, and possibly with some special properties such as having specific eigenval…

Entanglement detection via some classes of measurements
Shu-Qian Shen, Ming Li, Xue-Feng Duan
Based on the mutually unbiased bases, the mutually unbiased measurements and the general symmetric informationally complete positive-operator-valued measures, we propose three sepa…
