Abstract

The properties of the output probe field in a qubit-embedded system containing two coupled cavities are investigated theoretically. A strong pump field and a weak probe field drive the left cavity. The right cavity couples the mechanical oscillator through the photothermal effect. Simultaneously, a qubit couples the right cavity and the mechanical oscillator through Jaynes-Cummings coupling. Coupled-resonator induced transparency (CRIT) is realized in the bare coupled cavities firstly. When considering the photothermal effect, photothermally induced transparency (PTIT) can also be achieved. Further, when a qubit is inserted, the qubit-assisted induced transparency (QIT) is demonstrated. Tunable optical response, along with slow-fast light at different frequencies, is shown by adjusting the system coupling strengths and frequency detunings. Especially, we demonstrate the group delay in the PTIT can also be manipulated by the photon tunneling between the double cavities.

具有光热效应的量子比特嵌入耦合腔的可调透明度

从理论上研究了包含两个耦合腔的量子比特嵌入式系统中输出探针场的性质。一个强泵场和一个弱探针场驱动左腔。右腔通过光热效应与机械振荡器耦合。同时，一个量子比特通过詹尼斯-卡明斯耦合将右腔和机械振荡器耦合起来。首次在裸耦合腔中实现了耦合腔诱导透明。当考虑光热效应时，还可以实现光热诱导透明（PTIT）。此外，当量子比特被插入时，量子比特辅助诱导透明（QIT）被证明。通过调节系统耦合强度和频率失谐，可调谐光响应以及不同频率下的快慢光。特别是，我们证明了PTIT中的群延迟也可以通过双腔之间的光子隧穿来控制。

期刊介绍： Since its first formulation quantum chemistry has provided the conceptual and terminological framework necessary to understand atoms, molecules and the condensed matter. Over the past decades synergistic advances in the methodological developments, software and hardware have transformed quantum chemistry in a truly interdisciplinary science that has expanded beyond its traditional core of molecular sciences to fields as diverse as chemistry and catalysis, biophysics, nanotechnology and material science.
