Title
(EN) HYBRID QUANTUM-CLASSICAL COMPUTER FOR VARIATIONAL COUPLED CLUSTER METHOD
Abstract
(EN)

A hybrid quantum classical (HQC) computer, which includes both a classical computer component and a quantum computer component, solves linear systems. The HQC decomposes the linear system to be solved into subsystems that are small enough to be solved by the quantum computer component, under control of the classical computer component. The classical computer component synthesizes the outputs of the quantum computer component to generate the complete solution to the linear system.
