  • PHD Student Vacancy in NWO-funded Perspectief programme Optical Wireless Superhighways

    The Programme

    In the NWO-funded Perspectief programme Optical Wireless Superhighways, new perspectives can be opened for wireless communication which will offer unprecedented capacity, connection density, privacy, and energy efficiency. Five universities and a variety of industries are joining forces to explore these opportunities at all length scales: ranging from ultra-long links between satellites to short links within indoor rooms. We are looking for enthusiastic PhD students to join our programme.

    For the area of secure communication, we are inviting candidates having a solid background in quantum optics, optical communication, integrated photonics or related, as for instance learned from a successfully finished MSc in Physics with a relevant MSc project.

    Your Project

    In this project, focusing on physical layer security, we will demonstrate authentication for quantum and classical communication links with Physical Unclonable Functions (PUFs), remotely read out via a single-spatial-mode. We will use a new class of PUFs that can be read out through standard optical fibres or free-space links. Our implementation of single-mode PUFs exploits the time/frequency domain for the encoding challenge / response space. Together with the fabrication of PUFs, we will develop tools to generate challenge-forming few-photon light pulses and to validate PUF responses at the few-photon level, with the aim of a proof-of-principle demonstration using the terrestrial free-space optical link developed by consortium partners.

    Supervisor, host group, collaborators.

    Your research will be performed within the newly established Adaptive Quantum Optics (AQO) chair in the MESA+ Institute for Nanotechnology at the University of Twente. Your supervisor will be Prof. Pepijn Pinkse (AQO). We work closely together with our colleagues in the program, especially at the TU/e. We hope to fill this position in the beginning of 2022.

    Our offer

    The University of Twente offers a stimulating work environment in an area of applied, forefront research. When fulfilling a PhD position at the UT, you will get the status of junior scientist. You will have an employment contract for the duration of 4 years and can participate in all employee benefits the UT offers. The gross monthly salary starts with € 2443,- in the first year and increases to € 3122,- in the fourth year of your employment. Additionally, the University of Twente provides excellent facilities for professional and personal development, a holiday allowance (amount to 8%), an end of year bonus of 8.3%. A high-quality training programme is part of the agreement. The research has to result in a PhD thesis at the end of the employment period.

    Questions regarding these positions can be directed to Pepijn Pinkse. Please send your application with c.v. (preferable with contact information for at least two academic references) to the group secretary, Nicole Meinster,

  • Postdoctoral researcher in integrated photonic quantum information processing

    The Adaptive Quantum Optics group at the University of Twente is looking for a two-year postdoctoral researcher in integrated photonic quantum information processing.


    Quantum photonics is one of the leading platforms for quantum computing, being one of the few to have demonstrated a quantum advantage and having excellent scalability as well as operation at room temperature. In particular, integrated photonics is a crucial technology for large-scale quantum photonic interference.

    At the University of Twente, we combine expertise in integrated photonics with expertise on both theoretical and experimental quantum optics to carry out innovative research into the fundamentals and applications of photonic quantum interference. Our vision is to do the fundamental research necessary to build large-scale quantum optical systems that can help solve real-world problems. Some of our recent highlights include theoretical work on the USTC quantum advantage demonstrations, the experimental demonstration of the world’s largest quantum photonic processor, and first demonstration of quantum photo-thermodynamics.  We are supported in these efforts by a long-standing collaboration with our spinout company QuiX Quantum BV, who produce world-best photonic processors with the unique combination of low loss and high component density achievable with SiN photonic waveguides.

    In this project, adaptive techniques will be developed to design photonic processors which are more robust to fabrication errors, as well as better strategies for programming those processors. These processors will then be used to implement novel applications of photonic quantum information processing which we have devised in our group.


    We are looking for a candidate with proven expertise (in the form of a PhD) in experimental quantum optics, including first-author publications. The candidate must have good professional team-work skills and proficiency in English, and must be open to collaboration with industry. Advantageous qualities in a candidate are: expertise in theoretical quantum optics, experience in leading research projects, and experience in project management / research grants. The candidate is expected to take a leading role in operating the quantum information processing experiment on which the work will be performed, and to support and guide the PhD students working on this setup. We can offer teaching opportunities as desired by the candidate.


    We are looking for a candidate to start as soon as possible. The salary will be according to the collective bargain­ing agreement for Dutch universities with generous fringe bene­fits such as vacation allowance and end-of-year bonus.
