A Syndrome-Extraction Framework for Distributed Lattice Surgery on Arbitrary Rotated Surface-Code Layouts
Researchers propose a syndrome-extraction framework for lattice surgery between surface-code patches placed in separate quantum-computing modules. The method is intended to cope with inter-module gates that are noisier than local gates and with extra hook-error paths introduced when layouts merge across a module boundary. It is described as applicable to arbitrary rotated surface-code layouts.

If circuit-level simulations confirm the framework's performance under realistic noisy inter-module links, it could provide a reusable scheduling layer for early modular surface-code demonstrations without per-layout syndrome-extraction redesign.
Modular architectures exist at small scale, and lattice surgery is a leading route to fault-tolerant operations; a general syndrome-extraction method for noisy inter-module links removes a layout-specific barrier, but adoption depends on validation against hardware noise models.
