Gorini–Kossakowski–Sudarshan–Lindblad equation in different bases: Application to driven-dissipative two- and multilevel systems

An open quantum system can be described by a master equation, of which one of the most popular is the Gorini–Kossakowski–Sudarshan–Lindblad (GKSL) equation. We revisit the description of driven-dissipative quantum systems, focusing on the appropriate choice of the system’s basis and the respective transformations. We consider the GKSL equation in different bases and calculate the dynamics for a qubit and for a qudit. An appropriate choice of the basis is a fundamental problem for the theoretical consideration of open quantum systems and provides an opportunity to obtain the desired evolution in practice.
