Quantum Network Control

Optimize entanglement distribution and swapping in multi-hop quantum networks. Based on sequential vs simultaneous entanglement swapping analysis (arXiv:2605.04047).

Core Concepts

Entanglement Swapping Strategies

Sequential Swapping:

• Nodes act on local state information only
• Each hop waits for previous hop to complete
• Simpler but higher latency
• Lower resource requirements per node

Simultaneous Swapping:

• Multiple nodes perform Bell measurements concurrently
• Requires global coordination or pre-agreed schedules
• Lower latency but higher resource demands
• Better throughput for long-distance links

Progressive Swapping to the Middle (PSM): (Updated 2026-06-02, arXiv:2605.31493)

• Establish entanglement in parallel on all segments, then progressively swap toward the middle
• Minimizes memory holding time: O(log n) vs O(n) for sequential
• Specifically adapted for networks with imperfect quantum memories
• When to use: Multi-hop networks where memory decoherence is the bottleneck (T_coh < (n-1) × t_swap)
• Key advantage: Memory-aware scheduling accounts for heterogeneous node coherence times
