Levitated quantum electromechanics with charged nanoparticles — •Lukas Martinetz1, Klaus Hornberger1, and Benjamin A. Stickler2 — 1University of Duisburg-Essen, Faculty of Physics, 47048 Duisburg, Germany — 2Imperial College London, Quantum Optics and Laser Science, London SW7 2AZ, United Kingdom
We propose an all-electrical platform for quantum experiments with charged nanoparticles of arbitrary shape and charge distribution. Each nanoparticle is levitated in a Paul trap, where its motion can be cooled resistively [1,2] and interfaced coherently with superconducting circuitry. We derive the effective potential of the ro-translational macromotion in the trap and develop a Raman-like pulsed interference protocol, which enables generating and observing spatial superpositions of the nanoparticles. This approach complements conventional optomechanical methods, providing a platform for generating entanglement between several nanoparticles and opening the door for networking levitated nanoparticles into hybrid quantum systems.
