Hhl Algorithm For Solving Linear Systems Of Equations In this article, we introduce a new quantum algorithm for solving linear systems based on the gradient descent method. Abstract linear systems of equations lie at the foundation of numerous problems in science, engineering, and data analytics, forming the computational backbone of numerical simulation, optimization, and machine learning. classical algorithms such as gaussian elimination and iterative solvers scale poorly for large, sparse, or ill conditioned systems. quantum algorithms, beginning with the.
Hhl Algorithm For Solving Linear Systems Of Equations In this paper, two quantum algorithms are proposed to solve quantum linear systems of equations with coherent superposition, and their specific quantum circuits are constructed. More precisely, a quantum linear system solver (qlss) takes as input an n × n complex matrix a together with a complex vector b of size n, and outputs a pure quantum state | x that is an ε approximation of the normalized solution vector of the linear system of equations a x = b. The harrow hassidim lloyd (hhl) algorithm, introduced in 2009, is a landmark quantum algorithm for solving systems of linear equations of the form ax=bax=b, where aa is an n×nn×n matrix and bb is a vector13. This chapter defines the quantum linear system problem and reviews direct quantum algorithms for solving linear systems of equations, such as the harrow–hassidim–lloyd (hhl) algorithm, and discusses conditions for efficient implementation.

This paper presents a system for solving binary valued linear equations using quantum computers. the system is called mod2vqls, which stands for modulo 2 variational quantum linear solver. as far as we know, this is the first such proposal. the design is a classical–quantum hybrid. Hhl’s speedup of solving linear equations can be applied to a variety of scientific fields. most prominently, this algorithm is impactful for machine learning and big data.
