We present a universal comprehensive theory concerning (i) the spontaneous (bath-induced) emergence of quantum entanglement in multipartite systems immersed in thermal environments (“baths”) and (ii) dynamical control aimed at manipulation or protection of this entanglement over times long enough for its applications. The theory allows for bath-enabled quantum computing (QC) protocols in the presence of decoherence and its dynamical control.
