摘要
测量在量子理论中具有特殊作用：通过坍缩波函数，它可以实现诸如隐形传态等现象，从而改变约束幺正演化的“时间箭头”。当集成于多体动力学中时，测量可导致时空量子信息的涌现模式，超越表征平衡或非平衡相的既定范式。在当今 NISQ 处理器上，由于噪声、硬件限制以及量子测量的随机性，该物理现象的实验实现具有挑战性。在此我们应对上述每个实验挑战，并在多达 70 个超导量子比特上研究测量诱导的量子信息相。通过利用空间与时间的互换性，我们使用对偶映射以避免电路中途测量，并以统一方式访问潜在相的不同表现——从纠缠标度到测量诱导隐形传态。我们通过将实验测量记录与经典模拟数据相关联的解码协议，获得了相变的有限尺寸特征。这些相表现出对噪声的截然不同敏感性，我们借此将固有的硬件限制转化为有用的诊断工具。我们的工作展示了一种在当前 NISQ 处理器极限尺度上实现测量诱导物理的方法。
