Noise and deviation effects in a bichromatic Raman white light cavity

Qingqing Sun, M. Selim Shahriar, M. Suhail Zubairy

We analyze the effects of noise and parameter deviations in a bichromatic Raman type white light cavity, with potential applications in precision measurements such as gravitational…

Entanglement criteria and nonlocality for multi-mode continuous variable systems

Qingqing Sun, Hyunchul Nha, M. Suhail Zubairy

We demonstrate how to efficiently derive a broad class of inequalities for entanglement detection in multi-mode continuous variable systems. The separability conditions are establi…

Quantum coherence in a degenerate two-level atomic ensemble: for a transition $F_{e} = 0 \leftrightarrow F_{g} = 1$

Ying Gu, Qingqing Sun, Qihuang Gong

For a transition $F_{e} = 0 \leftrightarrow F_{g} = 1$ driven by a linearly polarized light and probed by a circularly light, quantum coherence effects are investigated. Due to the coherenc…
