Derivation of the Lindblad generator structure by use of the Itô stochastic calculus
Abstract
We use the Itô stochastic calculus to give a simple derivation of the Lindblad form for the generator of a completely positive density matrix evolution, by specialization from the corresponding global form for a completely positive map. As a byproduct, we obtain a generalized generator for a completely positive stochastic density matrix evolution.
