Quantum physics provide unprecedented possibilities for quantum sensing and quantum metrology. By exploiting quantum correlations or genuine quantum states such as squeezed states, it becomes possible to go beyond fundamental limits for sensing imposed by the shot noise. This research direction at GQC is novel for the University of Geneva, and will directly benefit from the collaboration of several experimental and theoretical groups with an internationally-recognized expertise in quantum materials, quantum information theory, and manipulation of light-matter interactions at the quantum scale. Applications for sensing biological systems and for assessing temperatures of nanoscale devices belong to current research projects at GQC.
