Distributed Quantum Computing with Slow Interconnects

Research demonstrates that multiple quantum processing units (QPUs) connected by slow interconnects can surpass the performance of a single QPU, overcoming a key bottleneck in distributed quantum computing—the rate of entanglement production. The study proves that links generating a specific, scalable number of Bell pairs—O(t/ln t)—are sufficient to enable efficient distributed quantum computation, even with slower entanglement generation times.
