Quantum Memory Process with a Four-Level Atomic Ensemble

Xiong-Jun Liu, Hui Jing, Mo-Lin Ge

摘要:

本文详细研究了双$Λ$原子系综中光子的量子存储技术。提出了利用该技术产生两个不同的量子探测场及其纠缠态的新方法。研究了除暗态子空间外的更大的零简并类,证实了该模型的绝热条件。我们将单模量子存储技术推广到多模探测场的情况,揭示了在本系统中两个量子化脉冲之间的精确脉冲匹配现象。

英文摘要:

We examine in detail the quantum memory technique for photons in a double $Λ$ atomic ensemble in this work. The novel application of the present technique to create two different quantum probe fields as well as entangled states of them is proposed. A larger zero-degeneracy class besides dark-state subspace is investigated and the adiabatic condition is confirmed in the present model. We extend the single-mode quantum memory technique to the case with multi-mode probe fields, and reveal the exact pulse matching phenomenon between two quantized pulses in the present system.
