Abstract

We show that every quantum computation can be described by a probabilistic update of a probability distribution on a finite phase space. Negativity in a quasiprobability function is not required in states or operations. Our result is consistent with Gleason's theorem and the Pusey-Barrett-Rudolph theorem.

摘要

我们证明，每一个量子计算都可以由有限相空间上概率分布的概率更新来描述。在态或运算中并不需要准概率函数中的负性。我们的结果与格莱森定理和普西-巴雷特-鲁道夫定理相一致。
