Simple derivation of the lindblad equation
Webb19 okt. 2014 · used in deriving the Lindblad master equation. Therefore, such maps have more complicated generators of evolution. 8.The mapping from master equation to CPTP map is not unique. That is, many master equations can generate the same CPTP map. 9.The Lindblad master equation is only one generator of open system dynamics. It is … WebbThe Lindblad equation can be obtained by [math]\displaystyle{ \mathcal{L}(\rho) = \mathrm{lim}_{\Delta t \to 0} \frac{\phi_{\Delta t}(\rho)-\phi_0(\rho)}{\Delta t} }[/math] which, by the linearity of [math]\displaystyle{ \phi_t }[/math], is a linear superoperator. [math]\displaystyle{ \phi_{t+s}(\rho) = e^{\mathcal{L}s} \phi_t(\rho). }[/math]

WebbThe Lindblad Master equation ¶ The standard approach for deriving the equations of motion for a system interacting with its environment is to expand the scope of the system to include the environment. The combined quantum system is then closed, and its evolution is governed by the von Neumann equation (2)
WebbIn this paper, we consider the application of quantum reservoir engineering in quantum metrology. More precisely, we are concerned with a system setup where a sequence of atoms constructing the “time-varying” quantum reservoir interact, in turn, with the trapped field in a cavity through the Jaynes–Cummings Hamiltonian.
