PhD student position

Quantum-coherent microwave-optical conversion

Ref. 2019-09

Project description

We are seeking a highly motivated candidate for a PhD position in the project HOT – “Hybrid Optomechanical Technologies,” an FETProactive Horizon 2020 project funded by the European Union.

The aim of this project is to exploit recently developed fabrication capabilities for two materials with exceptional optical properties, GaP and BaTiO3 (BTO), to create a quantum-coherent, bidirectional transducer between microwave and optical qubits and to explore the architectural and information theoretic possibilities afforded by such devices. The ability to coherently convert microwave photons to optical photons is an outstanding scientific and technological challenge of particular relevance to quantum computing and future quantum networks. The work involves simulation, design, and fabrication of highly miniaturized photonic devices, laser-based optical characterization, and high-speed electronic and cryogenic measurements.

The PhD student will work in the Quantum Technologies group at IBM Research GmbH and be mentored by Dr. Paul Seidler.

The successful candidate will enjoy an internationally competitive salary and work with collaborative and creative groups in an exclusive research environment.

The position is available immediately.


  • A Master’s degree in engineering or physics
  • An outstanding academic record
  • Good communication and English language skills

Preference will be given to applicants with at least one publication in a peer-reviewed journal. The applicant should have a theoretical understanding of quantum optics. Previous research experience in optics, numerical simulation or nanoscale fabrication would be beneficial.


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