DPRQ: A Dynamic Programming-based Qubit Routing Algorithm for Collective Communication in Distributed Quantum Computing
A preprint introduces DPRQ, a dynamic programming-based qubit routing algorithm aimed at collective communication in distributed quantum computing. It identifies inter-node communication as a key bottleneck because entanglement distribution is inefficient and error-prone, and proposes that optimized routing can reduce this overhead.

If DPRQ benchmarks favourably against heuristic routers, distributed quantum compilers and quantum networking stacks could adopt dynamic-programming routing as a compile-time pass to reduce entanglement distribution overhead for multi-node circuits within the next two years.
The algorithm targets a known bottleneck with a formulation that fits existing compilation pipelines; the main precondition is validation of its routing cost and runtime on representative distributed circuits, which is feasible near-term and could prompt integration into software stacks for quantum data centres.
