论文摘要
辐射级联发射相关的光子对，为生成纠缠的光子提供了途径。因此，在半导体中实现了具有杂质原子的辐射级联反应，这是一个领先的量子光生成平台，将为开发纠缠的光子对来源提供新的途径。在这里，我们在Znse量子井中的杂质原子络合物中表现出辐射级联反应。发射的光子显示出明显的时间相关性，显示了时间 - 级联的顺序。我们的结果将ZNSE中的杂质原子建立为使用辐射级联反应的光子量子技术的潜在平台。
Radiative cascades emit correlated photon pairs, providing a pathway for the generation of entangled photons. The realization of a radiative cascade with impurity atoms in semiconductors, a leading platform for the generation of quantum light, would therefore provide a new avenue for the development of entangled photon pair sources. Here we demonstrate a radiative cascade from the decay of a biexciton at an impurity-atom complex in a ZnSe quantum well. The emitted photons show clear temporal correlations revealing the time--ordering of the cascade. Our result establishes impurity atoms in ZnSe as a potential platform for photonic quantum technologies using radiative cascades.
