Cavity-mediated long-range interactions for multiparticle entanglement and quantum simulation – CLIMAQS

Photon-mediated interactions between atoms coupled to an optical cavity are emerging as a powerful tool for engineering many-body Hamiltonians and entangled states. In our project, theorists and experimentalists will collaborate closely to investigate the dynamics of long-range interacting atomic spin systems and to develop robust production and characterization methods for spatially distributed quantum entanglement which is a resource for multi-parameter quantum metrology. This is made possible by an innovative experimental platform currently approaching completion at LKB, which combines a fiber Fabry-Perot microcavity for strong coupling to each of ~100 atoms in a 1D chain with state-of-the-art atomic tweezer techniques for single-atom addressing and detection. Furthermore, this setup will also be a unique platform for quantum simulations of exotic transport phenomena.
