Quantum computing necessitates quantum error correction (QEC) to protect information and enable the execution of practically relevant, deep quantum algorithms. However, the substantial overheads in qubit number, gates, and measurements pose significant challenges for near‑term scalability. To address this issue, developing novel code designs and noise‑tailored circuit-compilation strategies is essential for minimizing QEC resource requirements. In this talk, I will first introduce state‑of‑the‑art QEC using neutral atom qubits. I will then discuss recent advances in hardware‑efficient high-rate quantum memories—specifically quantum Low‑Density Parity‑Check (LDPC) codes [1]—for both static and reconfigurable neutral atom arrays. Following this, I will present a practical pathway toward high‑rate quantum computation, including a novel gate‑based protocol for addressable, transversal logical operations via gate teleportation with these codes [2]. Finally, time permitting, I will discuss a new protocol for faster and lower-depth error correction using three‑qubit gates [3] and present preliminary results leveraging atom loss as a resource for error correction.
