QuPort: Topology-, Port-, and Congestion-Aware Compilation for Modular Multi-QPU Quantum Systems

Soumyadip Sarkar, Subhasree Bhattacharjee

QuPort's TPCCAP finds circuit partitions for multi-QPU systems that jointly minimize cut distance, port overflow, and link congestion on a three-level graph.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The main partitioning method, TPCCAP, optimizes the implemented objective formed by weighted cut distance, communication-port overflow, and routed link-load congestion.

C2weakest assumption

That minimizing the weighted combination of cut distance, port overflow, and congestion on the three-level graph model will produce mappings that are meaningfully better on actual modular quantum hardware, without any reported hardware validation or calibrated cost functions.

C3one line summary

QuPort introduces a three-level graph model and TPCCAP optimizer for compiling circuits on modular multi-QPU systems while balancing topology, port usage, and link congestion.
