Volume of the space of qubit channels and some new results about the distribution of the quantum Dobrushin coefficient
Attila Lovas, Attila Andai
The simplest building blocks for quantum computations are the qbit-qbit quantum channels. In this paper we analyse the structure of these channels via their Choi representation. Th…
