Kraus representation for density operator of arbitrary open qubit system
arXiv:quant-ph/0311091 · doi:10.1134/S1054660X06110041
Abstract
We show that the time evolution of density operator of open qubit system can always be described in terms of the Kraus representation. A general scheme on how to construct the Kraus operators for an open qubit system is proposed, which can be generalized to open higher dimensional quantum systems.
