PhD Position in Quantum Physics and Precision Spectroscopy

Updated: 2 months ago
Job Type: Temporary
Deadline: 01 Feb 2023

Are you a highly-motivated student 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, 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 ).

What are you going to do?

You will work in a team that develops a new platform for precision spectroscopy based on quantum logic. In close collaboration with the LaserLab at the Free University in Amsterdam (VU), you will develop new ion traps that can be used for precision spectroscopy of simple atomic and molecular ions. By comparing the results to state-of-the-art calculations, we can probe for physics beyond the standard model. We will develop new quantum enhanced methods to improve the sensitivity of our measurements beyond state-of-the-art. The project will consist of several interrelated sub-projects aimed at:

  • Develop new ion traps to be used for quantum logic spectroscopy
  • Perform quantum logic spectroscopy in new ways in particular for studying quantum many body physics and quantum chemistry in atom-ion mixtures
  • Using optical tweezers to control the coupling between general spectroscopy and detection ions
  • You will work in a large team consisting of other PhD students, post docs and several master students based both at UvA and VU. Theory support will be supplied by the group of Dr. Arghavan Safavi-Naini of the Quantum Software research center (https://www.quantumsc.nl/ ). The work will involve setting up optics, lasers and electronics as well as programming and possibly microfabrication.
