We are searching for a motivated and interested PhD-student, with a degree in physics or related topics or with experience in quantum technology, spectroscopy, and/or laser physics, who wishes to work with us in the international and stimulating environment of the joint Quantum Metrology group at LaserLaB Amsterdam.

This project aims to develop a new experimental apparatus that enables quantum enhanced sensing in trapped barium ions for tests of electroweak theory. At the basis of the project lies a unique high-precision radio frequency ion trap in which single Ba+ ions will be confined and cooled to their motional ground state. With optical standing waves the individually ions will be addressed to drive an extremely weak parity forbidden transition. In order to detect the signals from driving such a weak transition, quantum entangled states will be used that reject external perturbations. Based on measurements of atomic parity violation in Ba...
