Qubit ZooIntroduces Floquet codes — dynamical quantum error-correcting codes where the codespace emerges from a periodic sequence of two-body measurements rather than a fixed stabilizer group. The honeycomb Floquet code achieves topological protection using only weight-2 measurements.
Key Results
- Codespace defined by periodic measurement cycle, not static stabilizers
- Honeycomb lattice with 3-step XX/YY/ZZ cycle
- Only weight-2 measurements (vs weight-4 for surface code)
- Effective code after one cycle is topologically equivalent to toric code
