Query: Robust M{\o}lmer-S{\o}renson gate for neutral atoms using rapid
  adiabatic Rydberg dressing   The Rydberg blockade mechanism is now routinely considered for entangling
qubits encoded in clock states of neutral atoms. Challenges towards
implementing entangling gates with high fidelity include errors due to thermal
motion of atoms, laser amplitude inhomogeneities, and imperfect Rydberg
blockade. We show that adiabatic rapid passage by Rydberg dressing provides a
mechanism for implementing two-qubit entangling gates by accumulating phases
that are robust to these imperfections. We find that the typical error in
implementing a two-qubit gate, such as the controlled phase gate, is dominated
by errors in the single atom light shift, and that this can be easily corrected
using adiabatic dressing interleaved with a simple spin echo sequence. This
results in a two-qubit M{\o}lmer-S{\o}renson gate. A gate fidelity $\sim 0.995$
is achieveable with modest experimental parameters and a path to higher
fidelities is possible for Rydberg states in atoms with a stronger blockade,
longer lifetimes, and larger Rabi frequencies.
