Vacancy: Integrated Quantum Key Distribution (Open)

Posted on 1/3/2024


The Photonics Research Group has been granted funding for advancing the future deployment of quantum key distribution (QKD). Nanophotonics and heterogeneous integration constitute two strength of the photonics research group that are ideal for up scaling the fabrication of QKD transmitters and receivers. This position is focused on measurement device independent QKD transmitters [1] and more advanced all-optical circuits acting as quantum repeaters [2,3].

Job Description

The candidate will be responsible for the research work including design, modelling, and complete characterization of the quantum ICs. The candidate will work together with and provide guidance to a small team of PhD-students working in the same project.

Responsibilities include:

  • Performing research in an independant way
  • Reporting on the research to supervisor and collaborators
  • Communication to peers at conference and via journal publications

Candidate Profile

  • At the starting time of the contract, the applicant must hold a PhD in physics, physics engineering or photonics engineering.
  • Good knowledge of optics and/or quantum information.
  • Active, hands-on experience with quantum photonics is highly recommended. Deep theoretical understanding of what is and is not feasible in quantum photonics is major plus.
  • Proficient level in English

Benefits include mandatory health insurance, laptop, travel to conferences.

About Us

The project will take place primarily at the University of Ghent in the photonics research group (PRG). PRG has pioneered the field of integrated photonics and keeps on enriching that technology, especially using integration of other materials and functionalities. It hosts a fully equipped measurement infrastructure (single photon detectors, higher power lasers, cryostat, ...), a cleanroom facility, and an extensive simulation infrastructure. The group is also an affiliated lab of IMEC: one of the world leading research institutions in microelectronics. The photonics research group hosts 12 professors, 15 postdocs and 50+ PhD students of many nationalities.
