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…

Optimal Bounds on Functions of Quantum States under Quantum Channels
Chi-Kwong Li, Diane Christine Pelejo, Kuo-Zhong Wang
Let be quantum states and be a scalar function such as the trace norm, the fidelity, and the relative entropy, etc. We determine optimal…
