- Abstract: For a prototype quadratic Hamiltonian describing a driven, dissipative
system, exact matrix elements of the reduced density matrix are obtained from a
generating function in terms of the normal characteristic functions. The
approach is based on the Heisenberg equations of motion and operator calculus.
The special and limiting cases are discussed.

We develop a general framework to linearize the von-Neumann equation rendering it in a suitable form for quantum simulations.
We show that one of these linearizations of the von-Neumann equation corresponds to the standard case in which the state vector becomes the column stacked elements of the density matrix.
A quantum algorithm to simulate the dynamics of the density matrix is proposed.
