Non-Abelian Geometric Quantum Memory with Atomic Ensemble
Y. Li, P. Zhang, P. Zanardi +1
We study a quantum information storage scheme based on an atomic ensemble with near (also exact) three-photon resonance electromagnetically induced transparency (EIT). Each 4-level…

Group Velocity of a Probe Light in an Ensemble of Lambda Atoms under Two-Photon Resonance
Y. Li, C. P. Sun
We study the propagation of a probe light in an ensemble of -type atoms, utilizing the dynamic symmetry as recently discovered when the atoms are coupled to a classical control…
