Research Scientist in Quantum Light Detectors

We are recruiting a Scientist to join us to research and develop quantum detector technology to sense single photons. Based on semiconductor avalanche photodiodes, our technology has applications in quantum key distribution, quantum networks, and quantum sensing, all of which we are developing here at Toshiba Europe Limited. The role requires extensive skills in semiconductor heterostructure and device design, and proven cleanroom fabrication experience, in order to lead production of novel devices together with partners in academia and industry. The successful candidate will also be responsible for characterisation and measurement of quantum detectors, and work within a highly accomplished team to integrate them into applications.


  • Leading design and development and processing of novel quantum light detectors
  • Coordination with partners in academia and industry on detector fabrication
  • Electro-optical characterisation and measurement of quantum detectors
  • Wider engagement through scientific dissemination and publications
  • Working as part of a team, and with partners in academia and industry

Essential requirements:

  • PhD in Electrical Engineering, Physics, or a related discipline
  • Proven original research in quantum light detection, semiconductor devices, or related field
  • Experience of semiconductor fabrication design, including lithography mask design
  • Extensive cleanroom device fabrication experience
  • Optoelectronic device characterisation experience
  • Excellent collaborative communication skills
  • Capability of both creative, independent work and working within an interactive team.
  • Desire to acquire new skills and work with new technologies

Desirable requirements:

  • Experience with single photon avalanche photodiode development
  • Task leadership experience
  • Semiconductor device simulation software
  • Knowledge of PCB design and assembly
  • GHz frequency electrical measurements
  • Good knowledge of computer control programming environments, e.g., LabVIEW/Python

Background information:

Based in Cambridge, UK, Toshiba Europe Ltd. has a proven track record in research and development of quantum devices for such systems, including the first single and entangled photon LEDs, and the first GHz operation of 1550nm single photon avalanche diodes, and are a leading developer of quantum key distribution systems.
