Unfolding a quantum master equation into a system of real-valued equations: Computationally effective expansion over the basis of SU(N) generators
(Physical Review E;Volume 100, Issue 5 — November 2019, Journal article; Peer reviewed, 2019-11-11)Dynamics of an open N-state quantum system is often modeled with a Markovian master equation describing the evolution of the system density operator. By using generators of SU(N) group as a basis, the density operator can ...
