Jobs

Postdoc and PhD positions are available at LaserLaB of the Vrije Universiteit Amsterdam (The Netherlands) at several projects that focus on fundamental physics through laser precision measurements of He+, HD+, H2+, HD and HT. For more information see: LINK

Postdoctoral and PhD positions at RWTH Aachen and Forschungszentrum Jülich in the theoretical quantum technology group in the area of quantum information processing, with a focus on quantum error correction, fault-tolerant quantum computing and physical implementations. Please contact m.mueller@physik.rwth-aachen.de

Permanent positions (at postdoc level) are available to develop optical and microwave atomic clocks at the UK’s National Physical Laboratory. Contact: patrick.gill@npl.co.uk Details. 

2 Research Fellow Positions 
in Quantum Technology for Fundamental Physics at in the ITCM-Group at the University of Sussex. The research project is part of the UK ‘Network of clocks for measuring the stability of fundamental constants’ consortium. The consortium aims to build a network of dissimilar clocks to search for spatio-temporal changes in fundamental constants. The team at Sussex investigate transitions in molecular nitrogen ions to measure changes in the proton-to-electron mass ratio. Our partners in the network are the National Physical Laboratory, Imperial College London, the University of Birmingham and the University of Sussex. More information here or contact Matthias Keller (m.k.keller@sussex.ac.uk).

A PhD position at Infineon on 1k Qubit Ion Traps. Details

The TITAN collaboration seeks 3 Postdoctoral Fellows to support its high-precision experiments at TRIUMF. Four on-line ion traps (a linear Paul trap, MR-TOF, EBIT, and Penning trap) are used to prepare and measure radioactive ion beams to study nuclear structure, nuclear astrophysics, and fundamental interactions. Please read here or contact Ania Kwiatkowski, aniak@triumf.ca, for more information.

A postdoctoral research associate to work on an electron electric dipole moment measurement using ultracold molecules. Details

postdoc position is available in the Patterson group at the University of California, Santa Barbara.  We are a relatively new group, developing new techniques for action spectroscopy in molecular ions.  A near-term goal of the research is realizing non-destructive spectroscopic identification of single polyatomic ions. Contact davepatterson@ucsb.edu for more information. Postdoc and PhD positions for projects focussed on quantum computing with trapped ions are available at the University of Oxford, please contact Chris Ballance (chris.ballance@physics.ox.ac.uk).
