Rapid generation of high fidelity, dissipation-stabilized dimerized chain

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