Evolving FT-Weave Interfaces for Multi-Logical-Qubit Code Blocks

Determine how the FT-Weave stage interfaces should evolve for high-rate quantum low-density parity-check architectures when scheduling changes from individual logical patches to multi-logical-qubit code blocks.

Background

FT-Weave is presented as a stage-aware real-time compilation framework that separates static planning from dynamic resource assignment, routing, and correction handling. The paper instantiates it on architectures in which individual logical patches are the primary units of preparation, movement, and execution.

The Outlook discusses extending the framework to high-rate qLDPC architectures and related hardware systems. Such codes may encode multiple logical qubits per block, creating new static placement decisions and dynamic dependencies when operations or measurement outcomes couple encoded qubits. The unresolved issue is how FT-Weave’s existing stage interfaces should be redesigned to accommodate this change in the unit of scheduling.
