PhD in quantum enhanced sensing with trapped ions (QUESTIONs project)

Research / Academic

In this project you will develop a scalable trapped-ion quantum sensor based on Ba+ for quantum enhanced sensing and metrology. You will built-up lasers that enable cooling and spectroscopy of a scalable number of ions. You will design and develop optical systems that enable individual addressing of single ions and realise versatile quantum gates. You will implement advanced experimental methods to generate entangled states that enable long coherence times and explore quantum enhanced precision spectroscopy. You will apply the developed techniques to precise magnetic field sensing and frequency metrology.


  • degree in MSc or engineering degree in physics (or something comparable)
  • an affinity for experimental physics, with preferably knowledge on atomic physics and quantum optics
  • a strong motivation and a good team spirit!

As a university, we strive for equal opportunities for all, recognising that diversity takes many forms. We believe that diversity in all its complexity is invaluable for the quality of our teaching, research and service. We are always looking for talent with diverse backgrounds and experiences. This also means that we are committed to creating an inclusive community so that we can use diversity as an asset.

We realise that each individual brings a unique set of skills, expertise and mindset. Therefore we are happy to invite anyone who recognises themselves in the profile to apply, even if you do not meet all the requirements.

Salary Benefits:

A challenging position in a socially engaged organisation. At VU Amsterdam, you contribute to education, research and service for a better world. And that is valuable. So in return for your efforts, we offer you:

  • a salary of € 2.770,00 (PhD) and maximum € 3.539,00 (PhD) gross per month in the fourth year, for a full-time employment
  • an employment contract of initially 1 year. If there is sufficient perspective, this will be extended to a total of 4 years. Your dissertation at the end of the fourth year forms the end of your employment contract.

We also offer you attractive fringe benefits and arrangements. Some examples:

  • A full-time 38-hour working week comes with a holiday leave entitlement of 232 hours per year. If you choose to work 40 hours, you have 96 extra holiday leave hours on an annual basis. For part-timers, this is calculated pro rata.
  • 8% holiday allowance and 8.3% end-of-year bonus
  • contribution to commuting expenses
  • discounts on collective insurances (healthcare- and car insurance);
  • optional model for designing a personalized benefits package
