量子测量对于量子计算具有普适性。目前存在两种基于测量的量子计算模型：单向量子计算器是由Briegel和Raussendorf提出的，而通过投影测量的量子计算仅由Nielsen提出。第二个模型的最新发展是基于状态转移而不是隐形传态。从这一发展有限，但近似的量子普适家庭的观测量展示，其中包括只有一个两个量子比特的观测，而其他的是一个量子比特的观测。在这篇文章中，提出了一个无限的，但精确的量子普适家庭的观察，也包括只有一个两量子比特的观察。本文的其余部分致力于比较这两种基于测量的量子计算模型，即单向量子计算和仅通过投影测量的量子计算。从这个比较，这是由希拉克和Verstraete发起的更密切和更自然的联系出现在这两个模型之间。这些紧密的联系导致了基于测量的量子计算的统一观点。
Quantum measurement is universal for quantum computation. Two models for performing measurement-based quantum computation exist: the one-way quantum computater was introduced by Briegel and Raussendorf and quantum computation via projective measurements only by Nielsen. The more recent development of this second model is based on state transfers instead of teleportation. From this development a finite but approximate quantum universal family of observables is exhibited which includes only one two-qubit observable while others are one-qubit observables. In this article an infinite but exact quantum universal family of observables is proposed including also only one two-qubit observable. The rest of the paper is dedicated to compare these two models of measurement-based quantum computation i.e. one-way quantum computation and quantum computation via projective measurements only. From this comparison which was initiated by Cirac and Verstraete closer and more natural connections appear between these two models. These close connections lead to a unified view of measurement-based quantum computation.
