Two postdoctoral positions at the Institute of Microelectronics of Barcelona

Two postdoctoral positions at the Institute of Microelectronics of Barcelona,
IMB-CNM-CSIC and the Quantum Computing Technology Group – IFAE

The Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) and the Quantum Computing
Technologies (QCT) group at the Institute for High Energy Physics (IFAE) offer two postdoctoral
positions within the projects Micro-nano fabrication technologies for mitigation of radiation
effects (MINARE) and Nanofabrication-Enhanced Superconducting Qubit Quality (NESQQ),
both funded by the Spanish Ministry of Science and Innovation.

Project MINARE, as part of coordinated project IRCQ, aims at overcoming detrimental effects on qubit
coherence caused by ionizing radiation by exploring on-chip solutions based on new materials and advanced processing. The project includes establishing the production and consolidation of conventional superconducting circuits based on aluminum thin films, while proposing two unconventional strategies for reducing quasiparticle effects or managing internal losses.

Project NESQQ aims at the improvement of superconducting qubit quality by combining
nanofabrication and noise filtering techniques. The project will look at improving qubit coherence time and parameter reproducibility by reduction of on-chip microscopic flux and charge noise following state-of-the-art nanolithography and processing techniques. This approach includes reducing the presence of spurious twolevel fluctuators and quasiparticles by, on one hand, dedicated surface passivation techniques and, on the other hand, introducing novel materials in the qubit device production.

Interested candidates are expected to:
Hold a PhD in Physics, Materials Science, Nanotech, Quantum, HEP, etc.
Be experienced in experimental techniques, in at least two of the following areas:

  • Superconducting devices,
  • Thin film materials,
  • Micro/nanoelectronic device fabrication,
  • Microwave quantum coherent control,
  • Cryogenics

Applications and requests for further information should be sent to and
Interested researchers should include an updated CV with a letter of intent or motivation, and
could arrange for 3 letters of recommendation. The appointments will be for 2 or 3 years terms.
Proposed start of the appointment: Late Fall 2022 / Early 2023
Closing date: Open until the positions are filled

IMB-CNM-CSIC and IFAE are equal opportunity employer committed to diversity in the workplace, and we welcome applications from all qualified candidates. Women are particularly encouraged to apply. Sending CVs to IFAE implies consent to the institute’s legal warning.
