Query: Three approaches for representing Lindblad dynamics by a matrix-vector
  notation   Markovian dynamics of open quantum systems are described by the L-GKS
equation, known also as the Lindblad equation. The equation is expressed by
means of left and right matrix multiplications. This formulation hampers
numerical implementations. Representing the dynamics by a matrix-vector
notation overcomes this problem. We review three approaches to obtain such a
representation. The methods are demonstrated for a driven two-level system
subject to spontaneous emission.
