PhD positions

Quantum Light Sources with Perovskite Nanocrystal Superlattices and Photonic Quantum Information Processing

Ref. 2021_035

Project description

The PhD positions are available in the Quantum Technology group in the field of Quantum Photonics at IBM Research Europe – Zurich. The positions are part of European Horizon 2020 funded projects targeting a new generation of nanomaterials-based quantum photonic devices. The projects involve the assembly of new nanomaterials (colloidal perovskite quantum dots) and the in-depth characterization of their opto-electronic properties down to the single photon level. Furthermore, the design, fabrication, and characterization of integrated or tunable microcavities in the strong light-matter interaction regime have to be carried out. Scientific objectives are non-classical light emission, multi-photon states and the development of coupled, on-chip polaritonic logic gates for ultrafast all-optical logic circuitry. All projects will be hosted at IBM Research Europe in Rüschlikon, Switzerland, and comprise strong, interdisciplinary collaboration with external partners that are part of the respective project consortia.


Candidates should have an outstanding background in quantum physics and material science and should have acquired a Master’s degree in physical chemistry, material science, physics or photonic engineering with outstanding success. A strong background in clean-room processing, optical spectroscopy and knowledge of nanophotonic simulations and device characterization will be beneficial.

Job offers

IBM offers a 3-year fellowship in line with the terms and conditions of the respective European H2020 framework program.


IBM is committed to diversity at the workplace. With us you will find an open, multicultural environment. Excellent flexible working arrangements enable all genders to strike the desired balance between their professional development and their personal lives.
