For the Communications Engineering Lab (CEL) at Karlsruhe Institute of Technology (KIT), we are currently seeking to recruit, starting February 1st, 2024 or later, limited to three years, one
Doctoral Candidate / Research Associate (f/m/d)
working on the development of error correction coding schemes for information reconciliation in QKD within the frame work of the European Marie Skłodowska-Curie Doctoral Training Network “QuNEST” on “Quantum Enhanced Optical Communication Network Security” (QuNEST Doctoral Candidate 3).
Research Programme Description
“QuNEST– Quantum Enhanced Optical Communication Network Security Doctoral Training” is hiring 11 Doctorate Candidates” to be funded by the Marie Skłodowska-Curie Actions (MSCA) Doctoral Networks. QuNEST is a highly interdisciplinary and intersectoral Doctoral Network composed of leading academic and industrial partners. The consortium consists of six academic institutions, namely: Eindhoven University of Technology, Technical University of Denmark (DTU), Karlsruhe Institute of Technology (KIT), University of L'Aquila, University of Warsaw and University of Geneva as well as the companies: ADVA Network Security, Exatel, IDQuantique, Infinera Germany, KEEQuant, NKT Photonics, Nokia Bell Labs France, Telecom Italia Mobile, Quantum Optical Technologies, Quantum Telecommunications Italy and VPIphotonics and involves seven different European countries. The diverse consortium provides a unique and timely opportunity to train students in quantum physics and optical communications.
The driving force for QuNEST is to provide high-level and highly collaborative training to 11 highly achieving Doctoral Candidates. This Doctoral Network is a highly multi-disciplinary, spanning areas of quantum physics, simulations, photonics, optical transmission, Quantum Key Distribution (QKD) protocols, implementation security, error correction algorithms, digital signal processing, networks and control, requiring cross-disciplinary and intersectoral training targeted at creating experts in this emerging multidisciplinary field. The QuNEST Doctoral Candidates will be trained by doing research, in which they will demonstrate the potential of combining quantum and classical optical data signals in a single fiber with the aim to develop ground-breaking and commercially attractive, short-to-medium term solutions targeting European industry leadership in this highly challenging sector. QuNEST will train much-needed future scientists and engineers who will design, build, deploy and operate the next generation quantum secured optical communications infrastructure.
The Doctoral Network program is designed to follow technical, scientific, and transferable skills, enabling the next generation of young researchers/engineers with excellent skills in understanding the challenges of quantum secure optical communications. All Doctoral Candidates will carry out secondments and placements with industrial partners at the earliest possible opportunity. Transferable skills and technical workshops from industrial partners will be central to the training of the Doctoral Candidates.
About the Host Institution
Karlsruhe Institute of Technology was established by the merger of the Forschungszentrum Karlsruhe GmbH and the Universität Karlsruhe (TH) on October 01, 2009. Karlsruhe Institute of Technology (KIT) is a public non-profit institution pursuing the tasks of a State University of Baden-Wuerttemberg and of a national research center of the German Helmholtz Association. KIT’s mission combines the three strategic lines of activity of research, higher education, and innovation. With about 9.600 employees and 23.500 students, KIT is one of the largest institutions of research and higher education in natural sciences and engineering in Europe. Engineering sciences, natural sciences, the humanities, and social sciences make up the scope of subjects covered by KIT. In high interdisciplinary interaction, scientists of these disciplines study topics extending from the fundamentals to application and from the development of new technologies to the reflection of the relationship between man and technology.
The Communications Engineering Lab (CEL) of KIT is a globally recognized, leading scientific and applied research institute focused on physical layer algorithms for optical, wireline and wireless communication systems. Research at the CEL mainly focuses on the field of robust and reliable data communications as well as on digital signal processing and information theory as its scientific foundations. Current research topics include, but are not limited to: channel coding for reliable communications, application of machine learning in communications, digital signal processing for communications, in particular optical communications, energy-efficient communications, quantum key distribution, and quantum error correction. Consistent with these research topics, co-operations in national and international research programs are pursued. Joint projects with industry and public customers complete our creative scientific work. Within the Faculty of Electrical Engineering and Information Technology, CEL is engaged in all levels of academic education. Basic and advanced concepts from the fields of transmission technology and signal processing are covered within CEL’s lectures and seminars. Graduates are familiar with the technological and scientific fundamentals of up-to-date communication networks.
- Project title: Development of error correction coding schemes for information reconciliation in QKD
- Host institution: Karlsruhe Institute of Technology (KIT)
- PhD enrolment: Karlsruhe Institute of Technology (KIT)
- Supervisors: Laurent Schmalen (KIT). Co-supervisor: Darko Zibar (Technical University of Denmark) Mentor: Amirhossein Ghazisaeidi (Nokia Bell Labs)
- Project title: Development of error correcting codes for information reconciliation in QKD
- Research objectives: You will design codes and protocols for reverse reconciliation in CV-QKD systems. This project significantly extends the state-of-the-art by investigating novel error correction methods for reverse reconciliation. You will design novel methods for error correction, based on a detailed information-theoretic analysis of the channel and the protocol. You will model the channel and aim for extremely low code rate codes. You will approach codes beyond traditional designs based on the models provided by the industrial partner. You will focus on extremely low complexity of the implementation with a focus on the extremely low SNR region. During secondments, you will help in experimentally verifying your codes in an extensive transmission DV/CV-QKD testbed, aiming to achieve record transmission distance and secret key rates.
- Expected results: 1) Error correction protocol for QKD schemes with shaped modulation formats designed to maximize secret key rates and transmission distances, 2) Experimental assessment of the protocol in conjunction with industrial partner, 3) Advanced channel code designs for QKD and extension towards DV-QKD schemes
