光与量子发射器相互作用产生的手性量子非线性仅能调制散射光子的相位，无法调制其振幅，可用于构建非互易光子元件、量子逻辑门和量子网络协议。本研究表明，添加第二束光子会彻底改变这一情况，实现相位和振幅的同时调制；不同光束间的相干光子转移能产生比标准对称相互作用更强的振幅调制，这在相干三光子放大中最为明显，研究预测其在手性几何结构中的峰值效率为30%，是对称结构效率的3倍。研究结果揭示了手性量子光学的新区域，为少光子能量下更高效的全光控制提供了途径。
英文摘要
Chiral quantum nonlinearities that arise when light interacts with quantum emitters are known to modulate only the phase but not the amplitude of scattered photons, enabling the creation of non-reciprocal photonic elements, quantum logic gates, and quantum network protocols. In this work, we show that the addition of a second photon beam drastically changes this picture, enabling both phase and amplitude modulation. Surprisingly, coherent photon transfer between the different beams enables a stronger amplitude modulation than standard symmetric interactions. This is most obvious in the coherent, three-photon amplification, which we predict peaks with a 30% efficiency in a chiral geometry, 3x the efficiency of the symmetric configuration. Our results uncover a new regime of chiral quantum optics and provide a route towards more efficient all-optical control at few-photon energies.
