Query: Optimal representation of quantum channels   This work shows an approach to reduce the dimensionality of matrix
representations of quantum channels. It is achieved by finding a base of the
cone of positive semidefinite matrices which represent quantum channels. Next,
this is implemented in the Julia programming language as a part of the
QuantumInformation.jl package.
