标题： Recycling Reflections for Perfect Photon Capture

摘要： 在光学腔中高效捕获光子对于量子网络和量子计算至关重要，然而单次通过的方法由于捕获窗口有限和耦合强度的限制，会遭受未捕获的反射，从而无法实现任意光子态的完美传输。 我们引入了一种双次通过的“投掷与接住”方法，该方法可回收初始反射以在无噪声情况下实现任意脉冲的完美捕获，并在固有损耗下提高保真度。 该方法还可扩展到光子发射，实现任意脉冲形状的设计。 这一进展为量子中继器、存储器和转换提供了显著改进，增强了量子信息处理的工具箱。 显示英文摘要

摘要： Efficient photon capture in optical cavities is essential for quantum networks and computing, yet single-pass methods suffer from uncaptured reflections due to finite capture windows and coupling strengths, precluding perfect transfer of arbitrary photonic states. We introduce a two-pass `pitch-and-catch' method that recycles initial reflections to achieve perfect capture of arbitrary pulses in the noiseless regime and enhances fidelity under intrinsic losses. The method extends to photon emission, enabling arbitrary pulse shaping. This advance offers significant improvements for quantum repeaters, memories, and transduction, enhancing the toolkit for quantum information processing.
