Clifford量子元胞自动机(Clifford quantum cellular automata, CQCAs)是一种特殊的量子元胞自动机,它结合了Clifford群运算进行时间演化。尽管它们是经典的可模拟的,但它们可以用作通用量子计算的基本构建块。这是由于与平移不变稳定状态及其纠缠特性的联系。我们将对CQCA作一个完整的介绍,并研究在CQCA作用下纠缠的产生。此外,我们将讨论cqca的有限结构和应用。
Clifford quantum cellular automata (CQCAs) are a special kind of quantum cellular automata (QCAs) that incorporate Clifford group operations for the time evolution. Despite being classically simulable, they can be used as basic building blocks for universal quantum computation. This is due to the connection to translation-invariant stabilizer states and their entanglement properties. We will give a self-contained introduction to CQCAs and investigate the generation of entanglement under CQCA action. Futhermore, we will discuss finite configurations and applications of CQCAs.
