Thermo-field entanglement description of Markovian two-state relaxation (opens in new tab)

arXiv:2601.12435v1 Announce Type: new Abstract: We present a unified description of symmetric two-state Markov relaxation and intrinsic entanglement dynamics based on thermo-field dynamics (TFD). A classical two-state Markov process is embedded into a dissipative two-level quantum system by identifying the Markov relaxation rate with the dissipation parameter in a von Neumann equation with a relaxation term. Using the reduced extended density matrix in the TFD formalism, we explicitly separa...
