基于测量的量子计算代表了一个强大而灵活的量子信息处理框架，它基于纠缠量子态作为计算资源的概念。最突出的应用是单向量子计算机，集群状态作为其通用资源。在这里，我们展示了基于测量的量子计算原理，使用确定性生成的簇态，在一个被捕获的钙离子系统中。首先，我们为量子计算实现了一套通用的操作。其次，我们展示了一系列基于测量的量子纠错码，并展示了它们随着码长增加而提高的性能。所提出的方法可以直接扩展到生成几十个量子比特的图状态。
Measurement-based quantum computation represents a powerful and flexible framework for quantum information processing, based on the notion of entangled quantum states as computational resources. The most prominent application is the one-way quantum computer, with the cluster state as its universal resource. Here we demonstrate the principles of measurement-based quantum computation using deterministically generated cluster states, in a system of trapped calcium ions. First we implement a universal set of operations for quantum computing. Second we demonstrate a family of measurement-based quantum error correction codes and show their improved performance as the code length is increased. The methods presented can be directly scaled up to generate graph states of several tens of qubits.
