       Advertising Entanglement Capabilities in Quantum Networks

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.

   No Schrodinger's cats were harmed in the creation of this document.

1.  Introduction

   Quantum networking is an emerging field using the strange (even
   counterintuitive) properties of quantum mechanics to bring new,
   useful capabilities to computing and 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,
