- Abstract: Realizing a large-scale fully controllable quantum system is a challenging
task in current physical research and has broad applications. Ultracold atom
and molecule arrays in optical tweezers in vacuum have been used for quantum
simulation, quantum metrology and quantum computing. Recently, quantum ground
state cooling of the center-of-mass motion of a single optically levitated
nanoparticle in vacuum was demonstrated, providing unprecedented opportunities
for studying macroscopic quantum mechanics and precision measurements. In this
work, we create a reconfigurable optically-levitated nanoparticle array in
vacuum. Our optically-levitated nanoparticle array allows full control of
individual nanoparticles to form an arbitrary pattern and detect their motion.
As a concrete example, we choose two nanoparticles without rotation signals
from an array to synthesize a nanodumbbell in-situ by merging them into one
trap. The nanodumbbell synthesized in-situ can rotate beyond 1 GHz. Our work
provides a new platform for studying macroscopic many-body physics.
