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.
QKD in Modern Telecommunications Networks: The successful applicant will be part of the MSCA doctoral network QSI (Quantum-Safe Internet) and will study telecom network designs and the co-existence of quantum and classical signals in optical networks as well as developing next-generation QKD systems to simplify the integration and optimise their performance in optical networks. One of the remaining challenges is to produce QKD network equipment that can easily be integrated with modern communications networks and enable the co-existence of classical and quantum channels, as well as a quantum network multiplexing many channels between many different transmitters and receivers. Full details can be found here.
Entangled two-photon absorption in atoms and molecules: The successful applicant will study different biomolecular and simple atomic samples to better understand the origins of the quantum advantage in entangled two-photon absorption (ETPA) – a quantum analogue to classical two photon absorption schemes. The first goal is to improve the performance of these experiments. This will include experimentally developing better entangled photon pair sources in different wavelength regimes as well as improved fluorescence collection and imaging schemes. They will also study plasmonic nanoarrays to improve absorption and fluorescence characteristics. The results of these studies should allow us to compare possible quantum solutions with existing classical applications. Full details can be found here.
Superconducting nanowire single-photon detector development: The successful applicant will work on expanding the frontier of superconducting nanowire single-photon detectors (SNSPDs). This will include the creation of novel designs and architectures, combined with a strong focus on developing new fabrication processes to improve the performance of such detectors. The candidate will work both in the state-of-the-art laboratories at the University of Geneva, and in the cleanroom at École Polytechnique Fédérale de Lausanne (EPFL). The detectors will subsequently be characterised in our state-of-the-art cryostats, before use in experiments either here at the university, or in collaboration with other institutions. Full details can be found here.
In general, 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 identify 2-3 people who may be contacted to provide recommendation letters.
