论文摘要
我们描述了识别众所周知的周期性语言家族的量子有限自动机的物理实现。实现利用了单光子的极化程度及其通过线性光学元件的操作。我们使用置信度放大技术来减少自动机的接受误差概率。值得注意的是，我们物理上意识到的量子有限自动机本身不仅有趣，而且事实证明这是许多量子有限自动机设计框架理论上在文献中定居的重要构建块。
We describe a physical implementation of a quantum finite automaton recognizing a well known family of periodic languages. The realization exploits the polarization degree of freedom of single photons and their manipulation through linear optical elements. We use techniques of confidence amplification to reduce the acceptance error probability of the automaton. It is worth remarking that the quantum finite automaton we physically realize is not only interesting per se, but it turns out to be a crucial building block in many quantum finite automaton design frameworks theoretically settled in the literature.
