Efficient Quantum Error Correction from Three Dimensional Qubit Control
A preprint studies the [[144,12,12]] bivariate bicycle qLDPC code on a neutral-atom architecture with native three-dimensional qubit control. It examines how the platform's 3D geometry could handle the code's nonlocal syndrome extraction, which is the main barrier to realizing its lower qubit overhead relative to surface codes. The work compares this approach to existing methods.

If the study identifies a viable 3D syndrome extraction schedule, neutral-atom platforms could attempt a 12-logical-qubit qLDPC demonstration within two years.
Neutral-atom arrays already support reconfigurable 3D atom movement and mid-circuit measurement, so the missing piece is a practical sequence for nonlocal stabilizer checks. A concrete code study showing that 3D control can implement these checks efficiently would lower the barrier to hardware tests of high-rate qLDPC codes.
