Coherently coupled mechanical oscillators in the quantum regime

ORAL

Abstract

We couple spectrally separated pairs of quantum harmonic oscillator modes of motion in linear multi-ion crystals via parametric modulation of the confining potential. The choice of the modulation determines which pair of modes are coupled together.  We realize the coherent exchange of single motional quanta between the coupled modes while controlling the timing, strength, and phase of the coupling. We demonstrate high fidelity quantum state transfer between modes and use the coupling to entangle motional modes and observe Hong-Ou-Mandel type interference. Controllable coupling of this type between harmonic oscillators can aid high-fidelity operations for quantum information processing with discrete and continuous variables, quantum simulations, and precision measurements. It can also enable cooling and quantum logic spectroscopy involving motional modes that do not couple directly to laser light.
