The Quantum Technologies group is part of the Applied Physics Department at the University of Geneva, which enjoys a high reputation internationally and is excellently equipped for performing world-class research. We have active collaborations with the international research community, and locally are home to a network of research groups also working on quantum memories and repeaters, macroscopic quantum systems, non-locality and entanglement, quantum thermodynamics, quantum optics theory, and biophotonics. We offer a highly attractive research environment and salaries according to Swiss standards.
We are always seeking outstanding candidates looking for PhD positions. Our group is exploring and developing quantum technologies such as photon sources and single photon detectors, and their application in quantum communication ranging from applied to more fundamental perspectives, as well as emerging cross-disciplinary applications. The candidates must have a completed masters degree in physics or related disciplines with excellent grades, be highly motivated, and enjoy working in an international team.
PhD Applications: Candidates should send an e-mail with a CV and motivation letter to either Hugo Zbinden or Rob Thew. Please also include 2-3 people who may be contacted to provide recommendation letters.
R&D nanofabrication scientist of superconducting single-photon detectors
The Quantum Technologies group in the department of Applied Physics at the University of Geneva, in collaboration with ID Quantique (IDQ), has developed a strong R&D program in the field of Superconducting Nanowire Single-Photon Detectors (SNSPD). The ongoing partners’ mission is to enable scientists and industrial users to create the future of quantum technologies using the best single-photon detectors. This program developed high-performance and commercial-grade SNSPDs with unique specifications. These detectors are now used in state-of-the-art quantum communication experiments, and a technology transfer to IDQ led to a successful commercialisation.
We are seeking applications to fill an opening for the role of an R&D nanofabrication scientist. Within an Innosuisse project, we aim at developing novel types of SNSPDs with improved performance through nanofabrication process and material development combined with innovative SNSPD designs. The project will be executed in close collaboration with IDQ, which will create synergies towards a commercialisation of the new developments.
The ideal candidate holds a PhD in a relevant physics and/or engineering field. As a forward-looking problem solver, you will be responsible for delivering creative and innovative solutions to complex problems in a collaborative manner. You will be taking initiatives and drive this project towards completion within the defined timeline and scope. Through a sustained and effective communication with all members of team and with external partners, you will ensure that the priorities are set and followed properly. You are interested in the application of R&D to product development.
Location: University of Geneva, Group of Applied Physics - Quantum Technologies. Frequent trips to CMi at EPFL in Lausanne, and regular visits to IDQ in Geneva.
Key functions and responsibilities:
- Lead the R&D and project management activities
- R&D activities: master the physics of SNSPDs, continuously develop/maintain/improve the nanofabrication process and testing tools to achieve the desired objectives, optimise the development cycle, proactively propose new development directions when necessary
- Project management activities: define detailed development plan and set priorities, coordinate with IDQ on a regular basis, execute within defined timeline, communicate clearly with stakeholders and partners, find and nurture external collaborations when necessary
- PhD in physics or engineering with a strong focus on nanofabrication, optoelectronic devices and materials development
- A strong record showing the ability to lead a complex scientific projects with ambitious objectives
