Abstract
Trapped ions provide a register of highly controllable qubits and quantum harmonic oscillators, formed by their internal states and quantized motion, respectively. In this seminar, I will describe how we synthesise interactions between these different subsystems and subsequently use them to unlock the full potential of the hybrid register for quantum information processing. More precisely, we implement qubit-conditioned nonlinear and multimode oscillator interactions [1,2], and then demonstrate how these interactions enable the exploration of novel quantum states [3] as well as serve as a powerful toolkit for quantum simulation of lattice gauge theories [4,5].
