The problem of mixed states geometric phases in open quantum systems through the quantum jumps method was discussed. Thus, this method can be applied for any system evolving under a Markovian master equation or, equivalently, under any trace preserving completely positive map.

Abstract
The problem of mixed states geometric phases in open quantum systems through the quantum jumps method was discussed. Thus, this method can be applied for any system evolving under a Markovian master equation or, equivalently, under any trace preserving completely positive map. Within this framework, it was shown that, it was possible to define and calculate a geometrical phase for an open system
