Trapped Atoms and Ions for Quantum Simulation, Quantum Information and Quantum Measurement

报告内容摘要

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”.
