Quantum optics with cold atomic gases
Abstract: Ultra-cold atomic gases can now be precisely controlled and manipulated in the quantum regime. In this talk, I will present our results on using ensembles of cold atoms, especially high-lyi...

How to grab an atom without squeezing it
Abstract: Research for cooling and trapping of atoms in the mid 1980s was mainly motivated to enable precise spectroscopic measurement. However, perturbation by the trapping force introduces sig-nifi...

Quantum Journal Club: Coherent and dynamic beam splitting based on light storage in cold atoms
Abstract: We demonstrate a coherent and dynamic beam splitter based on light storage in cold atoms. An input weak laser pulse is first stored in a cold atom ensemble via electromagnetically induced t...

Continuous-variable quantum correlation and quantum communication: Beyond Gaussi
Quantum information protocols, originally envisioned for two-state (qubit) systems, have also been extended to continuous variables (CVs). It is usually held that Gaussian squeezed state is an essenti...
