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.
