Description

Understanding the nature of correlated quantum many-body systems is the main purpose of modern condensed matter physics. Current booming quantum computing techniques offer a new way to treat these challenging systems: the quantum simulation approach. Using the quantum computer, which is a controllable quantum many-body system by itself, we can simulate other correlated quantum systems in which we have interests. However, since we are currently in the noisy intermediate-scale quantum (NISQ) era, specific algorithms need to be developed to maximally utilize current noisy quantum devices (NISQ devices). Here, I will introduce one of the main algorithms on NISQ devices, the variational quantum eigensolver (VQE), and its application to study correlated quantum many-body systems.
