PhD position Trapped Ions in Optical Tweezers

PhD @University of Amsterdam posted 2 hours ago

Job Description

Faculty of Science :14255
Total working timing : 38 hours
Are you a highly-motivated researcher looking for a post doc for performing state-of-the-art atomic physics experiments and developing quantum technology? Then we are looking for you.The hybrid atom-ion quantum systems lab, headed by Dr. Rene Gerritsma and Dr. Robert Spreeuw, is part of the Quantum Gases and Quantum Information (QGQI) cluster at the University of Amsterdam. The main focus of the group is to study the quantum dynamics in trapped ions while at the same time developing technology for emerging quantum applications, such as quantum computing and simulation.More information on our research can be found on the webpage (www.hyqs.nl).

This is what you will do

We will develop a new platform for quantum computing, based on trapped ions in combination with optical tweezers. We will explore the use of tightly focused laser beams and their interaction with crystals of trapped ions to realize new ways to prepare and control qubits, making particular use of the so-called optical Magnus effect, an optical analogue of the well-known classical Magnus effect that is for instance applied in football, causing ball trajectories to curve. In trapped ions, this effect can be used to implement state-of-the-art quantum gates. The tweezers can also be used to sub-Doppler cool the ion crystal and for qubit readout. We will also explore the scalability of the scheme by designing ion traps based on integrated photonics for tweezer delivery.

What we ask of you

  • at least 8 months of master project in experimental ultracold atom or trapped ion group;
  • good team working skills;
  • good English skills;
  • strong letter of recommendation from master project supervisor;

For MSCA PhD positions it is required that the applicant shall at the date of recruitment be in the first four years (full-time equivalent research experience) of their research careers and have not been awarded a doctoral degree. The applicant must not have resided or carried out her/his main activity (e.g. work or studies) in the Netherlands for more than 12 months in the three years immediately prior the recruitment date.

This is what we offer you

A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). The preferred starting date is 1 October 2025 or as soon as possible after that. This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.

Your application & contact

If you feel the profile fits you and you are interested in the job, we look forward to receiving your application by email to r.gerritsma@uva.nl and in addition by an online submission via the button below. We accept applications until and including 24.8.2025.

If you have any questions or do you require additional information? Please contact:

Rene Gerritsma, r.gerritsma@uva.nl and/or Robert Spreeuw, R.J.C.Spreeuw@uva.nl

Applications should include the following information (for the application through this website: all files besides your cv should be submitted in one single pdf file; for the application by email: simply describe everything except the CV in the email itself and attach your CV):

  • a detailed CV including the months (not just years) when referring to your education and work experience;
  • a short letter of motivation;
  • a link to your master thesis, if you already wrote it, or a short description of what it will contain;
  • the name and email address of your master thesis supervisor or another reference who can provide a letter of recommendation.
