报告摘要  Abstract
In the Hilbert space formulation, quantum states are density matrices, i.e., positive
semidefinite matrices with trace one, and quantum channels are trace preserving
completely positive linear maps on matrices. In this talk, we will present some results
on the existence of quantum channels with some special properties.
Open problems in constructing special types of quantum channel will be mentioned.
