论文摘要
光子量子相关性的出现通常与发射器紧密耦合到光子模式相关。在这里，我们表明半导体rydberg激子（仅弱耦合到自由空间的光模式）可以产生强烈的抗挡板磁场，即量子光。在Rydberg激素之间诱发成对偏光子散射事件之间的微米级激发阻碍，这种效果助长了这种效果。入射在激子共振上的光子被划分为蓝色和红色的双对，它们具有相对保护，从而免受吸收，从而占主导地位。我们证明，这种效应在存在其他声子耦合，强烈的非辐射衰减以及跨广泛的实验参数的情况下持续存在。我们的结果为从弱耦合半导体激子观察量子统计量铺平了道路。
The emergence of photonic quantum correlations is typically associated with emitters strongly coupled to a photonic mode. Here, we show that semiconductor Rydberg excitons, which are only weakly coupled to a free-space light mode can produce strongly antibunched fields, i.e. quantum light. This effect is fueled by micron-scale excitation blockade between Rydberg excitons inducing pair-wise polariton scattering events. Photons incident on an exciton resonance are scatted into blue- and red-detuned pairs, which enjoy relative protection from absorption and thus dominate the transmitted light. We demonstrate that this effect persists in the presence of additional phonon coupling, strong non-radiative decay and across a wide range of experimental parameters. Our results pave the way for the observation of quantum statistics from weakly coupled semiconductor excitons.
