We define and study a fidelity criterion for quantum channels, which we term the minimax fidelity, through a noncommutative generalization of maximal Hellinger distance between two positive kernels in classical probability theory. Like other known fideli-ties for quantum channels, the minimax fidelity is well-defined for channels between finite-dimensional(More)
In this paper we first introduce the Fock-Guichardet formalism for the quantum stochastic (QS) integration, then the four fundamental processes of the dynamics are introduced in the canonical basis as the operator-valued measures , on a space-time σ-field F X , of the QS integration. Then rigorous analysis of the QS integrals is carried out, and continuity(More)
