Functieomschrijving

The high-capacity optical transmission laboratory – Electrical Engineering at the Eindhoven University of Technology has an open post-doctoral position in the field of the coexistence of Quantum and classical signals.

Goal and Background - TU/e QKD testbed and development of evaluation site
At the TU/e campus, we are developing a world-class testbed to enable the integration of classical coherent optical transmission with Quantum key distribution (QKD) systems. QKD offers the means to increase the security of next-generation optical communication systems or even ensure unconditionally security in combination with one-time pad encryption. The interest in QKD has risen in recent years, primarily due to the rapid progress in computation hardware, lower cost of data storage, and maturity of quantum computing technologies. The most mature QKD systems are based on single-photon detection schemes; however, continuous variable (CV) QKD has recently received a lot of interest for several reasons [1,2,3]. It may be implemented with off-the-shelf hardware from coherent communication technology, promising low cost and integrability to classical optical coherent transmission networks. Quantum Delta [4] funds this particular project on developing Quantum Testbed under the CAT-2 programme on Quantum Network Testbed - https://quantumdelta.nl/accelerate-in-detail/

This novel testbed will address several critical applications with stringent key performance indicators (KPIs) and requiring high cybersecurity, e.g., robot-to-robot communication, fronthaul to a robot, robot-to-drone, broadcasting, city security, 3D-communications, 5G automated vehicle driving, to name but a few. As such the candidate will draw from current and ongoing EU and National Projects from several groups at TU/e on 5G, Quantum secured 5G networks BRAINE and Quantum secure authentication project - NWO SMOKE and others. All activities are cross-collaborating in setting up the Quantum test-environment.

Research Challenges in the Quantum Testbed Project
The Quantum Testbed will be rolled out across the TU/e campus using locally deployed optical fibres; besides, the testbed is expected to expand into a regional network interconnecting local nodes. Operating QKD alongside classical optical signals presents several challenges such as handling the impact of impairments such as loss, noise and scattering from classical optical channels.
 

Role
The candidate project will investigate new and efficient quantum key distribution protocols, multiplexing techniques to enable the coexistence of classical optical and quantum channels, including novel high-dimensional fibre-based encoding schemes. Besides, this project will aim at a fully-fledged co-propagation of classical and quantum light within the same optical fibre and will look further towards deploying such systems in a field-trial link. 
 

Work environment
Eindhoven University of Technology (TU/e) is one of Europe's top technological universities, in the heart of one of Europe's largest high-tech innovation ecosystems - the Eindhoven Brainport region. Research at TU/e is characterized by a combination of academic excellence and a strong real-world impact through close collaboration with high-tech industries.

The candidate will be employed within the Electro-Optical Communications Group, in particular within the high-capacity optical transmission laboratory (https://www.tue.nl/en/research/research-labs/high-capacity-optical-transmission-lab/). The candidate will strongly interact with the ECO group, which consists of over 70 researchers. This position is also embedded within the new Center for Quantum Materials and Technology (QT/e) at TU/e which consists of principal investigators from Applied Physics, Electrical Engineering and Mathematics & Computer science departments- https://research.tue.nl/nl/organisations/center-for-quantum-materials-and-technology-eindhoven-qte
 

Functie-eisen

We are looking, therefore for a strong researcher for applied research PostDoc/engineer to take up these challenges related to:
 

  • Implementation of a test environment for the evaluation of QKD with co-propagation with WDM systems,
  • Investigation of various multiplexing schemes for the co-propagation of classical and quantum light.
  • Development of the QKD setup based on various transmitter modulation and detection schemes
  • Develop knowledge of the impact of classical optical impairments with possible solutions
  • Develop and investigate suitable forward error schemes for QKD
  • Develop and support the roll-out of QKD nodes across the campus and regional testbeds in collaboration with dark fibre provider - SURF
  • Contribute towards the development of an integrated control plane
  • Co-Supervise and work with a team of PhD Students
  • Contribute to the definition of the roadmaps for research and assist the principal investigator in the preparation and submission of grants

The candidate for this position will contribute to the TU/e efforts in establishing the collaboration liaisons with QT/e but also with other projects and researchers in the project. The candidates will contribute to the related project reporting, scientific publication and dissemination activities and preparation of the proposal for a grant to national and European projects. The candidate is expected to interact with TU/e teams in efforts of establishing and operating the joint activities in the Eindhoven QKD testbed.
