 ## Time evolution ## Time evolution
-Under Hamiltonian evolution, the density matrix evolves according to the von Neumann equation $d\rho/dt = -i[H,\rho]/\hbar$. For open systems with environmental noise, this generalizes to the [[lindbald-equation|Lindblad master equation]], which adds dissipative terms describing decoherence and relaxation.+Under Hamiltonian evolution, the density matrix evolves according to the von Neumann equation $d\rho/dt = -i[H,\rho]/\hbar$.
