论文摘要
纳米技术[1,2]和单分子光谱[3-5]的最新进展为具有成本效益的有机量子光学技术铺平了道路，并有望在环境条件下运行现实生活。在这封信中，我们利用有机梯子型聚合物的$π$缀合的节段，与微腔形成相关的集体装饰状态，与兴奋的 - 帕顿 - 帕利顿冷凝物相关。我们通过单个光子探索了对宏观冷凝物波函数对宏观冷凝物波函数的有效方法。遵循BOSE统计，激子 - 果龙表现出了极端的非线性刺激[6]，我们设法在单光子水平上触发了这一刺激。依靠有机物的性质来维持带有高能分子振动的稳定激素，我们开发了一个原理，该原理允许在环境条件下进行单光子非线性操作，以在单光量子的基本限制下，为诸如次秒切换，放大，放大和全光逻辑等实现的实际实现打开大门。
The recent progress in nanotechnology [1,2] and single-molecule spectroscopy [3-5] paves the way for cost-effective organic quantum optical technologies emergent with a promise to real-life devices operating at ambient conditions. In this letter, we harness $π$-conjugated segments of an organic ladder-type polymer strongly coupled to a microcavity forming correlated collective dressed states of light, so-called of exciton-polariton condensates. We explore an efficient way for all-optical ultra-fast control over the macroscopic condensate wavefunction via a single photon. Obeying Bose statistics, exciton-polaritons exhibit an extreme nonlinearity undergoing bosonic stimulation [6] which we have managed to trigger at the single-photon level. Relying on the nature of organic matter to sustain stable excitons dressed with high energy molecular vibrations we have developed a principle that allows for single-photon nonlinearity operation at ambient conditions opening the door for practical implementations like sub-picosecond switching, amplification and all-optical logic at the fundamental limit of single light quanta.
