Research Position in Horizon-MSCA Doctoral Networks program on Quantum Enhanced Optical Communication Network Security

VPIphotonics sets the industry standard for end-to-end Photonic Design Automation comprising design, analysis and optimization of components, systems, and networks. Leveraging a strong history of innovation and expertise, we provide professional simulation software and design services for transmission systems, integrated photonics, optoelectronics, and fiber optics. Our award-winning solutions are used extensively in R&D and by product design and marketing teams at hundreds of corporations and academic institutions worldwide, targeting telecom, datacom, sensing, and signal processing applications. Please visit for more information.

We seek the talents of an R&D Engineer with an emphasis on quantum and classical optics communication systems. The position is based in Berlin, Germany, and supported by QuNEST, a Marie Skłodowska-Curie Actions (MSCA) Doctoral Network.

About QuNEST

Funded by the European Marie Skłodowska-Curie Actions (MSCA) Doctoral Networks (DN) program, QuNEST (Quantum Enhanced Optical Communication Network Security Doctoral Training) supports eleven Doctorate Candidates. This highly interdisciplinary and intersectoral Doctoral Network comprises leading academic institutions and companies from seven 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 the highly achieving Doctoral Candidates. The multi-disciplinary network spans areas such as quantum physics, photonics, optical transmission, Quantum Key Distribution (QKD) protocols, error correction, digital signal processing, networks, and control.

The DN program will teach technical, scientific, and transferable skills, aiming to enable the Doctoral Candidates to understand and master the challenges of quantum secure optical communications. In addition to their scientific projects, all fellows will benefit from further continuing education, including secondments, various training modules, transferable skills courses, and conference participation.

About the Research Project


• Modelling-based design of CV/DV-QKD systems in co-existence with classical opticaltransmission channels


• Extend existing simulation framework and model library for system-level simulations of DV/CV-QKD scenarios by developing missing modeling functions and simulation concepts to support awide range of QKD protocols.

• Investigate the impact of component imperfections and noise sources on the performance ofvarious QKD systems over fiber- or free-space-based links.

• Study the implementation of DV/CV-QKD systems over infrastructure with co-existing classicalchannels.


• Hosting and day-to-day supervision at VPIphotonics' premises in Berlin, Germany

• Co-supervision and Ph.D. enrolment by an academic partner in the QuNEST consortium

• Several 2-3 months long research secondments at academic and industrial QuNEST partners

  • The period of employment is 36 months. The targeted starting date is 01-Apr-2024 or later.
  • Doctoral Candidates are expected to travel to network partners for secondments and to participate in outreach activities.
  • To qualify, the candidate must not have resided or carried out his/her main activity in Germany for more than 12 months in the 36 months immediately before the recruitment date (unless as part of a compulsory national service or a procedure for obtaining refugee status under the Geneva Convention).
  • The candidate must not possess a doctoral degree (Ph.D.) at the recruitment date.

Application Procedure

Documents requested:

Complete CV (Europass format obligatory): The candidate is allowed to pursue a maximum of three positions in the QuNEST program. If more than one position is pursued, please clearly indicate with priorities all the positions applied for.

The motivation letter (max 1 page per position applied) should state why the applicant wishes to pursue the specific research and why the applicant is an ideal candidate for the position.

Scan of certificates showing BSc, MSc, and other courses followed, with grades and, if possible, a ranking.

Up to three recommendation letters and/or contact e-mail addresses with a brief professional description (title, position, relationship with applicant) of the referring person.

Up to two written scientific reports in English (e.g., MSc thesis, traineeship report or scientific paper)

Eligibility Statement:

To verify the MSCA requirements, the candidate clearly indicates the country/countries of main activity (work, studies, etc.) and country/countries of residence in the last five years. If you want to be considered for this position, send your application no later than 15-Feb-2024 to jobs.QuNEST(at)

Selection Process:

The selection process of invited candidates contains two phases:

• First, a wide range of selection practices will be applied (including expert assessment, face-to-face interviews, etc.) to evaluate the potential candidates.

• Then, QuNEST's Recruitment, Equality, Diversity & Inclusion Committee will evaluate the selected candidate.

The committee addresses gender balance and diversity issues within the entire Doctoral Network and needs to approve the selected candidate. QuNEST deals with a recruitment process based on the European principles of openness, fairness and transparency that guarantee a selection of candidates regarding merit and gender balance. All institutions have clear equal opportunities policies ensuring equal and fair recruitment and employment of men and women.
