We experimentally investigate the one-shot distillation of quantum coherence, which focuses on the transformations from a single copy of a given state into maximally coherent states under various incoherent operations. We present a general proposal to realize a type of strictly incoherent operations (SIOs) that can act on $N$-dimensional $(N \ge 2)$ states. This proposal is suitable for a variety of quantum devices. Based on a linear optical setup, we experimentally demonstrate that the proposed SIO successfully implements pure-to-pure state transformations, and thus the one-shot coherence distillation process is accomplished. The experimental data agree well with the theoretical results and clearly indicate the distillation fidelities, which bound the regions of different coherence distillation rates versus different superposition parameters of input states and different distillation errors.

一次性相干蒸馏实验演示：实现N维严格非相干操作

我们通过实验研究了量子相干的一次性蒸馏，它侧重于在各种非相干操作下从给定状态的单个副本到最大相干状态的转换。我们提出了实现一种严格不相干操作（SIO）的一般建议，该操作可以作用于$N$ -维$(N \ge 2)$状态。该提议适用于多种量子器件。基于线性光学设置，我们通过实验证明所提出的 SIO 成功实现了纯到纯状态的转换，从而完成了一次性相干蒸馏过程。实验数据与理论结果吻合良好，清楚地表明了蒸馏保真度，它将不同相干蒸馏速率的区域与输入状态的不同叠加参数和不同的蒸馏误差联系起来。
