Senior Scientist, Quantum Sensing (Cold-Atom Interferometry) at Q-CTRL, Sydney
Job Description
Q-CTRL’s Quantum Sensing Research team in Sydney is hiring a senior scientist in cold-atom interferometry. The team of about 30 covers theoretical and experimental atomic physics, atom interferometry, navigation modelling and Bayesian estimation. This role provides technical leadership for experiments on Q-CTRL’s atom-interferometer sensors: applying quantum control protocols on real hardware, improving sensitivity and robustness, and helping engineering teams make lab systems smaller and rugged enough for the field.
