量子图灵机的停机过程

On Halting Process of Quantum Turing Machine

Takayuki Miyadera, Masanori Ohya

摘要:

我们证明了没有算法来判断一个任意构造的量子图灵机在不同的计算分支上是否具有相同的时间步长。因此,我们不能避免量子图灵机中停机是概率性的概念。我们的研究结果表明,量子图灵机的停机方案和基于现有停机方案的量子复杂性理论应该重新审视。

英文摘要:

We prove that there is no algorithm to tell whether an arbitrarily constructed Quantum Turing Machine has same time steps for different branches of computation. We, hence, can not avoid the notion of halting to be probabilistic in Quantum Turing Machine. Our result suggests that halting scheme of Quantum Turing Machine and quantum complexity theory based upon the existing halting scheme sholud be reexamined.
