Offer Description

Optical signal modelling and characterization for QKD security analysis (QuNEST Doctoral Candidate 5)

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, Karlsruhe Institute of Technology, University of L’Aquila, University of Warsaw and University of Geneva as well as the companies: ADVA Network Security, Exatel, IDQuantique, Infinera Germany, KEEQuant (SME), NKT Photonics, Nokia Bell Labs France, Telecom Italia Mobile, Quantum Optical Technologies (SME), 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.

Job Description

  • Project title: Optical signal modelling and characterization for QKD security analysis
  • Host institution: University of Warsaw
  • PhD enrolment: University of Warsaw
  • Supervisors: Konrad Banaszek (University of Warsaw). Co-supervisor: R Thew (University of Geneva) Mentor: G. Boso (IDQuantique)
  • Research Objectives: DC5 will investigate effects of noise and impact on security of QKD protocols. Current security analysis for QKD has been carried out using models based on single modes carrying the signal. On the other hand, modulation, propagation, and demodulation of optical signals propagating in communication systems is interlinked with a plethora of intrinsically multimode noise effects and distortions for which an effective description is required to provide a bridge to new fibers. DC5 will work to maximise information throughput in a channel with QKD signals
  • Expected Results: 1) Effective models for QKD links incorporating noise and imperfections, resulting e.g. from interchange crosstalk and distortion introduced by the modulator/detector transfer functions, 2) Practical methods to quantify the security of QKD links based on accessible characteristics of the optical signals.
  • Secondments: The doctoral candidate secondments periods are planned at VPIphotonics, ADVA Network Security, IDQuantique


Conditions of employment

  • The successful candidates should receive an estimated expected gross salary of € 2378 (an additional annual premium could be paid), in accordance with the Marie Skłodowska-Curie Actions (MSCA) regulations for Doctoral Candidate researchers (the mobility allowance is included in the previous value). The salary values may change slightly due to the individual situation of the candidate. According to the MSCA regulation, if the recruited doctoral candidate has or acquires family obligations during the action duration, a family allowance will be added to the previous value, in case of eligibility.
  • The period of employment is 36 months. In addition to their individual scientific projects, all fellows will benefit from further continuing education, which includes secondments, a variety of training modules as well as transferable skills courses and attractive participation in conferences.
  • The Doctoral Candidates are expected to travel to network partners under three secondments for a typical duration of 2-6 months. Additionally, the Doctoral Candidates are expected to participate in outreach activities including, but not limited to, YouTube videos, social media updates, participation in public events and campaigns, as well as dissemination to popular press.
