- Abstract: Preparing and observing quantum states of nanoscale particles is a
challenging task with great relevance for quantum technologies and tests of
fundamental physics. In contrast to atomic systems with discrete transitions,
nanoparticles exhibit a practically continuous absorption spectrum and thus
their quantum dynamics cannot be easily manipulated. Here, we demonstrate that
charged nanoscale dielectrics can be artificially endowed with a discrete level
structure by coherently interfacing their rotational and translational motion
with a superconducting qubit. We propose a pulsed scheme for the generation and
read-out of motional quantum superpositions and entanglement between several
levitated nanoparticles, providing an all-electric platform for networked
hybrid quantum devices.
