腔增强光参量过程中的时间非对称双光子态

Temporally Asymmetric Bi-photon States in Cavity Enhanced Optical Parametric Processes

Usman A. Javid, Steven D. Rogers, Austin Graf, Qiang Lin

摘要:

在集成平台上产生和控制光的量子态已经成为可扩展量子技术的重要工具。芯片级光源,如非线性光学微腔已被证明可以有效地产生纠缠双光子态。然而,这些系统对光子的连续变量时间-能量纠缠几乎没有控制。我们证明了这样的控制,通过准备双光子态的非对称时间波函数,通过选择性地修改的腔模式的状态密度参与使用瑞利散射诱导的强耦合的谐振腔的光学模式的相互作用。这些态揭示了奇异的相干特性,并为芯片上的连续变量量子态工程提供了一条前进的道路。

英文摘要:

Generation and control of quantum states of light on an integrated platform has become an essential tool for scalable quantum technologies. Chip scale sources such as nonlinear optical microcavities have been demonstrated to efficiently generate entangled bi-photon states. However these systems have little control over the continuous variable time-energy entanglement of the photons. We demonstrate such control by preparing bi-photon states with asymmetric temporal wavefunctions by selectively modifying the density of states of the cavity modes taking part in the interaction using Rayleigh scattering-induced strong coupling of optical modes of a resonator. These states reveal exotic coherence properties and show a path forward for continuous variable quantum state engineering on a chip.
