Robust procedures for converting among Lindblad, Kraus and matrix representations of quantum dynamical semigroups
Robust procedures for converting among Lindblad, Kraus and matrix representations of quantum dynamical semigroups
Given a quantum dynamical semigroup expressed as an exponential superoperator acting on a space of N-dimensional density operators, eigenvalue methods are presented by which canonical Kraus and Lindblad operator sum representations can be computed. These methods provide a mathematical basis on which to develop novel algorithms for quantum process tomography—the …
