Query: Solution of the Lindblad Equation in the Kraus Representation   The so-called Lindblad equation, a typical master equation describing the
dissipative quantum dynamics, is shown to be solvable for finite-level systems
in a compact form without resort to writing it down as a set of equations among
matrix elements. The solution is then naturally given in an operator form,
known as the Kraus representation. Following a few simple examples, the general
applicability of the method is clarified.
