Abstract

   This document describes the use of link-state routing protocols on
   classical links in Quantum Networks.  It contains proposals for
   additions to the IS-IS and OSPF protocols in order for them to
   transport relevant information for a Quantum Network, specifically,
   for the creation and manipulation of entangled pairs.  The document
   will describe some of the necessary attributes and some suggestions
   of how this information may be used.

1.  Introduction

   Quantum networking is an emerging field using the strange (even
   counterintuitive) properties of quantum mechanics to bring new,
   useful capabilities to networking.  One of these is "entanglement"
   [8], where the state of a group of particles must be described as a
   unit -- it cannot be decomposed to the state of each particle
   independently.  Entangled pairs (often called EPR pairs, abbreviated
   here as EP) of particles can be used for quantum teleportation [10]
   and for quantum key distribution (QKD) [14].
