Abstract

<p>The recent progress of the hardware of the quantum computer are dramatic, and quantum computers with several hundreds of qubits might be within reach in a few years. This progress is motivating the world to search for applications of such devices. Here we give the overview of the recent development of algorithms for near-term, noisy quantum computers. This article is focused especially on so-called variational quantum algorithms where classical and quantum computers works together to solve a given task. The near-term quantum computers are expected to be applied in the area ranging from machine learning to quantum chemistry calculation. We also review some of the approaches to mitigate the noise effect.</p>
