We propose and analyze a method for efficient dissipative preparation of
matrix product states that exploits their symmetry properties. Specifically, we
construct an explicit protocol that makes use of driven-dissipative dynamics to
prepare the Affleck-Kennedy-Lieb-Tasaki (AKLT) states, which features
symmetry-protected topological order and non-trivial edge excitations. We show
that the use of symmetry allows for robust experimental implementation without
fine-tuned control parameters. Numerical simulations show that the preparation
time scales polynomially in system size n. Furthermore, we demonstrate that
this scaling can be improved to O(log2n) by using parallel
preparation of AKLT segments and fusing them via quantum feedback. A concrete
scheme using excitation of trapped neutral atoms into Rydberg state via
Electromagnetically Induced Transparency is proposed, and generalizations to a
broader class of matrix product states are discussed
