Cold atoms can now be routinely prepared and precisely controlled for the study of quantum physics.
In this talk, I will present our results
in using ensembles of cold atoms, especially high-lying Rydberg atoms to
study novel quantum effects and their applications in quantum optics.
We have developed experimental techniques and protocols to push the
limits on achieving long-lived (seconds) coherence in ground states and
rapid (sub-μs) quantum operations with strongly-interacting Rydberg
states. With these capabilities, we have demonstrated long-term storage
of photons, Rydberg blockade and many-body Rabi oscillations,
deterministic single photon source, magic trapping of Rydberg atoms,
Rydberg atom-light entanglement, and strongly-interacting quantum
memory.
