摘要
容错量子计算需要逻辑操作，这些操作在保持量子纠错保护的同时操纵编码信息。在平面表面码架构中，码形变和晶格手术提供了一条局域的、基于测量的途径来实现此类操作。在此，我们在一个107量子比特的超导量子处理器上实验实现了基于补丁的表面码逻辑处理的关键要素。我们首先实现了一个可重用的原语层，包括合并与分裂、补丁扩展与收缩，以及由畴壁和扭曲缺陷介导的形变。然后，我们组合这些原语来实现逻辑态路由、逻辑受控非门以及单量子比特Hadamard和相位门，它们共同构成一个生成Clifford群的集合。所有操作都在距离为三的旋转表面码补丁上实现，并采用多轮综合征提取和神经网络解码，无需后选择。我们的结果将超导表面码实验从受保护的逻辑存储器推进到主动的、基于补丁的容错逻辑操作。
