AI 中文摘要
我们理论提出了一种基于暗态极化激元场的量子存储器，该场由行波探测激光脉冲的原子态和光子态叠加形成，在固态介质中利用Λ能级方案电磁感应透明，施加主控制激光脉冲的驻波模式。我们展示了如何通过消除扩散引起的脉冲展宽来实现脉冲存储时间的增强。最后，我们提出了一项实验，该实验有助于实现探测脉冲在$\text{Pr}^{3+}:\text{Y}_2\text{SiO}_5$的超精细能级$^3\text{H}_4 \leftrightarrow ^1\text{D}_2$中的存储，该晶体在$4.5\text{ K}$下低温冷却。我们还讨论了探测脉冲量子态在延长的时间间隔内存储的多种应用。
英文摘要
We theorize a quantum memory based on the dark-state polariton field, formed by the superposition of atomic and photonic states of a travelling probe laser pulse under the application of standing wave modes of a dominant control laser pulse using a lambda-level scheme Electromagnetically Induced Transparency in a solid medium. We show how an enhancement in the storage time for the pulse is achieved by eliminating pulse broadening due to diffusion. At last, we propose an experiment that can help realize the storage of a probe pulse in the hyperfine levels $^3\text{H}_4 \leftrightarrow ^1\text{D}_2$ of $\text{Pr}^{3+}:\text{Y}_2\text{SiO}_5$, cryogenically cooled at $4.5\text{ K}$. We also discuss multiple applications the storage of the quantum states the probe pulse with a prolonged time interval must have.
