Effective cavities can be optically induced in atomic media and employed to strengthen optical nonlinearities. Here we study the integration of induced cavities with a photonic quantum gate based on Rydberg blockade. Accounting for loss in the atomic medium, we calculate the corresponding finesse and gate infidelity. Our analysis shows that the conventional limits imposed by the blockade optical depth are mitigated by the induced cavity in long media, thus establishing the total optical depth of the medium as a complementary resource.

光子量子门的感应腔

有效腔可以在原子介质中以光学方式引入，并用于增强光学非线性。在这里，我们研究基于里德堡封锁的诱导腔与光子量子门的集成。考虑到原子介质中的损失，我们计算了相应的技巧和门不忠。我们的分析表明，在较长的介质中，感应光腔会减轻由光学阻塞深度引起的常规限制，从而将介质的总光学深度确定为一种补充资源。
