Three Sheets, One Architecture: Inter-Sheet Logical Gates for K=4 Quantum Error Correction

2026-06-19

Abstract excerpt

<title>Abstract</title> <p>We present a CSS quantum error correcting code on the Face-Centered Cubic (FCC) lattice that combines surface-code-compatible K=4 connectivity with native inter-sheet logical gates between co-located CSS code blocks — a combination not previously achieved among well-studied codes. The construction has two parts. First, restricting the [[3L³, 2L³+2, 3]] FCC lattice code to a single triad...
