Optimal representation of quantum channels
arXiv:2002.05507 · doi:10.1007/978-3-030-50433-5_47
Abstract
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.
