量子Zeno阻塞下光子对的反聚束发射

Antibunched Emission of Photon-Pairs via Quantum Zeno Blockade

Yu-Ping Huang, Prem Kumar

摘要:

我们提出了一种新的方法,即“量子芝诺封锁”,用于管理在一般的非线性光学介质,如晶体,光纤,硅微环,和原子蒸气的光散射在几个光子的水平。使用这个工具,可以实现光子对的反聚束发射,从而导致强大的量子光学应用,如确定性纠缠产生而不需要预兆。在一个实际的实施方案中,使用一个芯片上的环形微腔浸没在铷蒸气中,我们估计,高保真纠缠光子可以按需产生在MHz的速率或更高,相应的$\gtrsim10^7$倍的改进,从国家的最先进的。

英文摘要:

We propose a new methodology, namely "quantum Zeno blockade," for managing light scattering at a few-photon level in general nonlinear-optical media, such as crystals, fibers, silicon microrings, and atomic vapors. Using this tool, antibunched emission of photon pairs can be achieved, leading to potent quantum-optics applications such as deterministic entanglement generation without the need for heralding. In a practical implementation using an on-chip toroidal microcavity immersed in rubidium vapor, we estimate that high-fidelity entangled photons can be produced on-demand at MHz rates or higher, corresponding to an improvement of $\gtrsim10^7$ times from the state-of-the-art.
