量子力学中数的态表示

The Representation of Numbers by States in Quantum Mechanics

Paul Benioff

摘要:

考察了复合量子系统的张量积态对数的表示。考虑限于长度L的k元表示和算术模k^{L}。本文描述了L重张量积Hilbert空间H^arith上的一种抽象表示,它是由数个状态和基本算术运算的算子组成的。定义了到基于物理参数的张量积空间H^{phy}上的酉映射,讨论了这两个空间之间的关系以及算法动力学对酉映射的依赖性.本文还讨论了用物理可实现的哈密顿量有效实现基本算术运算的重要条件。

英文摘要:

The representation of numbers by tensor product states of composite quantum systems is examined. Consideration is limited to k-ary representations of length L and arithmetic modulo k^{L}. An abstract representation on an L fold tensor product Hilbert space H^{arith} of number states and operators for the basic arithmetic operations is described. Unitary maps onto a physical parameter based tensor product space H^{phy} are defined and the relations between these two spaces and the dependence of algorithm dynamics on the unitary maps is discussed. The important condition of efficient implementation by physically realizable Hamiltonians of the basic arithmetic operations is also discussed.
