Trapped atoms
and ions have been demonstrated as model
experimental systems for simulating fundamental many-body quantum systems as
well as key resources for building quantum computers and quantum sensors. Indebted to laser cooling and atom
trapping techniques developed in the past two decades, currently neu-tral atoms can be cooled to less than one
mil-lionth of a de-gree Kel-vin above the ab-so-lute zero, and ions can be
frozen to the lowest quan-tum vibration states. This chill-ing world en-ables
us to manipulate and detect isolated quantum systems in a coherent way for
the purpose of quantum simulation, informa-tion, and measurement.
In this talk, I
will briefly review three representative works that we have implemented in
recent years for the above purpose. One is to use trapped 6Li
Fermionic atoms as quantum simulators for exploring universal strongly interacting physics of atoms, strongly correlated
materials, neutron stars, quark-gluon plasma, and black holes. The second
one is to use trapped Yb atomic ions to realize a scalable atom-photon
quantum network that
could store and process information in a way that could eclipse the
performance of conventional computers. The third one is to use a novel quantum
optical interferometer based on the interaction between light and the
external degrees of freedom of atoms for precision measurements of
gravitational field. Finally, I will provide a united vision that
trapped atoms and ions may provide us the favorite toys for the so called
“second quantum revolution”.
