摘要:
本文研究了在量子光学牛顿摆中的非马尔可夫环境中薛定谔猫态的转移。基于非马尔可夫主方程,我们表明猫态可以通过非马尔可夫共同环境的记忆效应纯转移,即使没有相邻腔体之间的直接耦合。通过解析和数值分析,证明了转移是非马尔可夫区域的独特现象。此外,我们还展示了环境参数对转移的影响。希望本文研究的猫态转移能进一步揭示非马尔可夫与马尔可夫环境的基本差异。
英文摘要:
In this manuscript, we study the Schrödinger cat state transfer in a quantum optical version of Newton's cradle in non-Markovian environment. Based on a non-Markovian master equation, we show that the cat state can be transferred purely through the memory effect of the non-Markovian common environment, even without any direct couplings between neighbor cavities. The mechanism of the environment induced cat state transfer is analyzed both analytically and numerically to demonstrate that the transfer is a unique phenomenon in non-Markovian regime. From this example, the non-Markovian environment is shown to be qualitatively different from the Markovian environment reflected by the finite versus zero residue coherence. Besides, we also show the influence of environmental parameters are crucial for the transfer. We hope the cat state transfer studied in this work may shed more light on the fundamental difference between non-Markovian and Markovian environments.
