The four-wave mixing process in atomic ensembles has many important applications in
quantum information. We review recent progress on the generation of optical quantum states …

Multimode entanglement is essential for the generation of quantum networks, which plays a
central role in quantum information processing and quantum metrology. Here, we study the …

摘要实验研究了铯蒸气中受激简并四波混频(DFWM) 产生的一对共轭光束的增益谱. 结果表明,
在简并二能级跃迁系统中, 只有当基态的角动量大于或等于激发态的角动量时 …

According to the fundamental laws of quantum optics, vacuum noise is inevitably added to
the signal when one tries to amplify a signal. However, it has been recently shown that …

The sharing of quantum resources between multiple parties allows for the creation of
quantum networks. Traditional four-wave mixing creates twin correlated beams of light. More …
