Low-Depth Quantum Error Correction via Three-Qubit Gates in Rydberg Atom Arrays

Quantum error correction typically requires deep circuits and large resources. We introduce a fast, low‑depth stabilizer readout for the surface code based on singly‑controlled two‑target (CZ2) gates. We show that this scheme preserves fault tolerance while reducing gate count and runtime, and is directly implementable in Rydberg atom arrays with time‑optimal pulses. Extensions to biased and erasure‑dominant noise, to quantum LDPC codes, and a survey of other optimal compilation strategies are also discussed.
