术语“超机”表示能够执行图灵机无法执行的任务的任何数据处理设备(理论上的或可以实现的)。我们提出了一个可能的量子算法的经典不可计算的决策问题,希尔伯特的第十个问题,更具体地说,我们提出了一个可能的超计算模型的基础上量子计算。我们的算法是受Tien D. Kieu,但是我们选择了无限方阱而不是(一维)简谐振子作为基础物理系统。我们的模型利用了量子绝热过程和与无限深方势阱相关联的动力学李代数su(1,1)的表示特性。
英文摘要:
The term `hypermachine' denotes any data processing device (theoretical or that can be implemented) capable of carrying out tasks that cannot be performed by a Turing machine. We present a possible quantum algorithm for a classically non-computable decision problem, Hilbert's tenth problem; more specifically, we present a possible hypercomputation model based on quantum computation. Our algorithm is inspired by the one proposed by Tien D. Kieu, but we have selected the infinite square well instead of the (one-dimensional) simple harmonic oscillator as the underlying physical system. Our model exploits the quantum adiabatic process and the characteristics of the representation of the dynamical Lie algebra su(1,1) associated to the infinite square well.
