Foliated Quantum Error Correction for Qudits

Quantum Physics 2026-07-15 v1

Abstract

We present a framework for foliating any Pauli-based quantum error-correcting code over prime-dimensional qudits. For any such code, we obtain a qudit graph state that can be measured to perform fault-tolerant measurement-based quantum computing. Such a paradigm is of interest in platforms such as photonics, where measurement-based protocols are natural and high-dimensional states are readily available. We discuss several examples for arbitrary prime dimension dd, such as the qudit toric code (stabilizer, CSS), the dd-dimensional perfect [[5,1,3]][[5,1,3]] code (stabilizer, non-CSS), and a straightforward dd-dimensional generalization of the CSS honeycomb code (dynamical, CSS). Under a simple error model, we numerically calculate thresholds for the foliated qudit toric code and demonstrate that they are comparable to the non-foliated version.
