In the Methods section of this Letter, owing to a typesetting error, the equations of motion using the Heisenberg picture were incorrectly shown as:

$${\hat{\dot{a}}}_{k}=\frac{i}{\hbar }\left[{\hat{H}}_{{\rm{int}}},{\hat{a}}_{k}\right]=-i{n}_{{\rm{\Omega }}}\,g\left({\hat{a}}_{k-1}+{\hat{a}}_{k+1}\right)$$

instead of as:
