Despite the many proposals to use dissipation as a resource to preparelong-lived entangled states, the speed of such entanglement generation isusually limited by the requirement of perturbatively small driving strengths.We propose a new scheme to rapidly generate many-body entanglement betweenmultiple spins coupled to a 1D bath stabilized by the dissipation into thebath. Our work stands in contrast to the current well known steady stateprotocols for entanglement generation in spins coupled to 1D baths that take aprohibitively long time, and exhibits a speedup over state-of-the-art protocolsby several orders of magnitude. Importantly, the protocol works even with alocal control Hamiltonian, and the timescale is independent of the system size.Our scheme can be applied to simultaneously generate a large number of spindimer pairs, which can serve as a valuable resource for quantum metrology andteleportation-based information processing.
