Special OQE Seminar Monday, August 6th 4-5 PM, Haus Room, 36-428 Professor Stephanie Wehner QuTech, Delft University of Technology Abtract: Towards a network stack for quantum networks In order to realize quantum networks that can support useful applications it desirable to develop a network stack to enable reliable communication and control. Such a stack could in principle be subdivided into a number of layers similar to the classical TCP/IP stack, or OSI model. The special features of qubits (and quantum entanglement), however, introduce entirely new design challenges that are not captured by any existing model or protocol suite. Here we present initial work towards designing such a stack. In this talk, we will in particular focus on presenting a link layer protocol, which uses a class of well known heralded entanglement generation schemes that have been realized in experiment at the physical layer. We proceed to introduce the first discrete event simulator for quantum networks - NetSquid - and use it to investigate the performance of the link layer protocol as an example. We present initial simulation results for the link layer protocol based on a system using NV centers in diamond, for a lab setup as well as the planned test link from Delft to The Hague. bio: Stephanie Wehner works as Antoni van Leeuwenhoek Professor at QuTech, Delft University of Technology. Her passion is communication in all its facets, and she has written numerous scientific articles in both physics and computer science. Stephanie is one the founders of QCRYPT, which has become the largest conference in quantum cryptography. She is Roadmap Leader of the Quantum Internet and Network Computing efforts at QuTech, and is the coordinator of the european Quantum Internet Alliance. From 2010 to 2014, her research group was located at the Centre for Quantum Technologies, National University of Singapore, where she was first Assistant and later Dean's Chair Associate Professor. Previously, she was a postdoctoral scholar at the California Institute of Technology in the group of John Preskill. In a former life, she worked in the classical internet industry and as a professional hacker.
