Packet Routing for the Quantum Internet

2026-07-07

AI Summary

This work addresses the lack of efficient packet routing mechanisms in the quantum internet by proposing a quantum packet routing architecture based on IPv6 extension headers. By repurposing underutilized IPv6 extension header fields, the approach enables the network layer to represent and process quantum superposition states and entanglement resources with minimal modifications to the existing IP protocol stack. The design supports essential quantum networking operations such as quantum teleportation and quantum-aware routing decisions. Crucially, the proposed framework maintains full compatibility with current IPv6 infrastructure, thereby not only enhancing the routing capabilities for quantum communication but also offering a practical, incremental pathway toward the realization of a scalable quantum internet.

Abstract

We present a new design for quantum packet routing within the emerging Quantum Internet, highlighting how a little-used feature of Internet Protocol Version 6 (IPv6), namely Extension Headers, can lead to a significant amount of quantumness within the IP layer. Taking a minimalist approach to alterations of established standards, we outline the changes required in order for quantum teleportation, quantum routing, and superpositions of these processes to be enabled. Relative to other proposals for routing within the Quantum Internet, the architecture we propose enables a wider range of outcomes allowed by quantum mechanics. We do not claim any optimally in our design, but rather a pathway to invoke new quantum routing outcomes via small additions to the current IPv6.
