用于数值QUBO公式化的范围相关哈密顿算法

Range dependent Hamiltonian Algorithm for numerical QUBO formulation

Hyunju Lee, Kyungtaek Jun

AI总结:

针对现有QUBO模型在量子计算机上求解线性系统时可用变量量子比特数过少的问题,本文提出一种按量子比特数划分整个域并构建各子区域QUBO模型的算法。

摘要:

随着量子计算机的出现和发展,各种能够比经典计算机更快求解线性方程和特征值的量子算法已被开发出来。Harrow-Hassidim-Lloyd算法是一种能在门模型量子计算机上求解线性方程的算法,但它受到量子RAM的使用以及根据量子计算机总量子比特数决定的矩阵大小限制的约束。最近,Jun和Lee开发了一种用于在量子计算机中求解线性系统和特征值问题的QUBO模型。然而,尽管他们的模型使用了2048个量子比特,可用于问题的变量量子比特数仅为64。为了解决这个问题,我们引入了一种算法,该算法可根据量子比特数将整个域的大小进行划分。我们还构建了与每个子区域相关的QUBO模型。

英文摘要:

With the advent and development of quantum computers, various quantum algorithms that can solve linear equations and eigenvalues faster than classical computers have been developed. The Harrow-Hassidim-Lloyd algorithm is an algorithm that can solve linear equations in a gate model quantum computer. Still, it is constrained by the use of quantum RAM and the size limit of the matrix according to the total number of qubits in the quantum computer. Recently, Jun and Lee developed a QUBO model for solving linear systems and eigenvalue problems in the quantum computer. However, even though their model uses 2048 qubits, the number of qubits for variables that can be used for the problem is only 64. To solve this problem, we introduce an algorithm that can be used by dividing the size of the entire domain according to the number of qubits. We also form a QUBO model related to each subregion.
