PhD and postdoc positions are available in the group of Prof. Stefan Willitsch at the University of Basel (Switzerland) on the development of quantum technologies for single trapped molecular ions and their application in precision spectroscopy.
Project description
In recent years, impressive advances in the quantum control of ultracold atoms and atomic ions have been achieved which enabled measurements with an unprecedented precision. Similarly precise experiments on molecules open up a range of new scientific perspectives including tests of new physical concepts, the implementation of new frequency standards, accurate evaluations of physical theories such as quantum electrodynamics and precise determinations of fundamental constants. They also lay the foundations for applications of molecules in the realm of modern quantum science such as quantum information and quantum sensing.
We have recently developed a new experimental approach enabling the readout of the quantum state of a single trapped molecular ion without destroying the molecule and indeed its quantum state itself. In the present project, the potential of this new method will be harnessed to perform highly sensitive and precise spectroscopic measurements on single moelcules. In the project, we will introduce completely new methods for molecular spectroscopy, further develop quantum technologies for molecular systems and establish new limits for the measurement precision of trapped molecules.

Candidates for the PhD positions should have a MSc degree in physics or physical chemistry, preferably with experience in experimental quantum science, quantum optics or spectroscopy. The PhD positions will be embedded in the Basel PhD program on “Quantum Computing and Quantum Technology” (QCQT, https://phdschoolqcqt.unibas.ch/en/) and be part of the Basel Quantum Center (www.quantum.unibas.ch).
Candidates for the postdoc positions should have a PhD in quantum science, quantum optics or atomic/molecular physics, preferably with a background in ion trapping.
Inquiries and applications should be sent to Prof. Stefan Willitsch (stefan.willitsch@unibas.ch) and include a cover letter, a curriculum vitae, a list of publications, transcripts of degree certificates and the contact details of at least two referees. Applications are accepted until all positions have been filled.
