量子有限态传感器

Quantum Finite State Transducers

R. Freivalds, A. Winter

摘要:

我们介绍量子有限态转换器(qfst),并研究他们计算的关系类。事实证明,它们与概率有限状态转换器共享许多特征,特别是关于空的不可判定性(至少对于低成功概率)。然而,就像它们的“小兄弟”量子有限自动机一样,qfst的能力是它们的概率对应物无法比拟的。我们通过讨论一些典型的例子来说明这一点。

英文摘要:

We introduce quantum finite state transducers (qfst), and study the class of relations which they compute. It turns out that they share many features with probabilistic finite state transducers, especially regarding undecidability of emptiness (at least for low probability of success). However, like their `little brothers', the quantum finite automata, the power of qfst is incomparable to that of their probabilistic counterpart. This we show by discussing a number of characteristic examples.
