Quantum nonlinear optics with an ion crystal in a cavity — •Robert Johne and Thomas Pohl — Max-Planck-Institute for the Physics of Complex Systems, Nöthnitzer Str. 38, 01187 Dresden, Germany

Ion crystals represent a versatile platform to engineer spin-spin interactions, which can be induced by an optical force and by coupling of the ions to common vibrational modes in the crystal [1]. This spin-spin interaction has been demonstrated and gives rise to study quantum phase transitions in the framework of quantum simulations [2]. Furthermore, coupling of an ion crystal to a cavity mode has been realized [3]. Here, we theoretically investigate an ion crystal embedded in a cavity, driven by coherent laser pulses. The interplay of cavity-ion coupling and the spin-spin interaction can be used to generate nonclassical spin as well as nonclassical light states with high fidelity. Moreover, this system holds the potential for engineering photon-photon interactions and as a quantum light-matter interface.
