因式分解问题的量子模拟

Quantum Simulation of the Factorization Problem

Jose Luis Rosales, Vicente Martin

摘要:

费曼对量子模拟器的处方是为一个可以充当计算机的系统找到一个哈密顿量。波利亚和希尔伯特猜想是通过厄米算子的谱分解来证明黎曼猜想。在这里,我们研究的问题分解成一个数的素因子,$N=xy$,使用这样的模拟器。首先,我们推导出物理系统的哈密顿量,模拟一个新的算术函数,制定的因式分解问题,这代表了计算机的能量。这个函数只依赖于$\sqrt N$下面的素数。我们精确地解决了量子系统的频谱,而不诉诸任何外部的特设条件,也表明它获得了,对于$x\ll \sqrt{N}$,一个预测的素数计数函数,这是几乎相同的黎曼的$R(x)$功能。它在解析数论中没有对应物,它的推导仅仅是模拟器的量子理论的结果。

英文摘要:

Feynman's prescription for a quantum simulator was to find a hamitonian for a system that could serve as a computer. Pólya and Hilbert conjecture was to demonstrate Riemann's hypothesis through the spectral decomposition of hermitian operators. Here we study the problem of decomposing a number into its prime factors, $N=xy$, using such a simulator. First, we derive the hamiltonian of the physical system that simulate a new arithmetic function, formulated for the factorization problem, that represents the energy of the computer. This function rests alone on the primes below $\sqrt N$. We exactly solve the spectrum of the quantum system without resorting to any external ad-hoc conditions, also showing that it obtains, for $x\ll \sqrt{N}$, a prediction of the prime counting function that is almost identical to Riemann's $R(x)$ function. It has no counterpart in analytic number theory and its derivation is a consequence of the quantum theory of the simulator alone.
