Abstract
We describe a simple quantum error correcting code built out of a time-dependent transverse field Ising model. The code is similar to a repetition code, but has two advantages: an N-qubit code can be implemented with a finite-depth spatially local unitary circuit, and it can subsequently protect against both X and Z errors if N≥ 10 is even. We propose an implementation of this code with 10 ultracold Rydberg atoms in optical tweezers, along with further generalizations of the code.
