  Entanglement between spatially distant qubits is perhaps the most
counterintuitive and vital resource for distributed quantum computing. However,
despite a few special cases, there is no known general procedure to maximally
entangle two distant parts of an interacting many-body system. Here we present
a symmetry-based approach, whereby one applies several timed pulses to drive a
system to a particular symmetry sector with maximal bipartite long-range
entanglement. As a concrete example, we demonstrate how a simple sequence of
on-site pulses on a qubit array can efficiently produce any given number of
stable nonlocal Bell pairs, realizable in several present-day atomic and
photonic experimental platforms. More generally, our approach paves a route for
novel state preparation by harnessing symmetry. For instance, we show how it
enables the creation of long-sought-after superconducting $\eta$ pairs in a
repulsive Hubbard model.
