Title: Quantum Computational Chemistry: Variational Quantum Eigensolver and the Design of Ansatz
Abstract: Over the past decade, quantum computing has experienced remarkable growth and development, opening up new possibilities for simulating molecular properties. In this talk, I will provide an overview of the fundamental concepts of quantum chemistry and the variational quantum eigensolver (VQE) algorithm. I will place particular emphasis on recent advancements in parameterized quantum circuits for VQE, including the unitary coupled-cluster (UCC) ansatz and the hardware-efficient ansatz (HEA). The talk will conclude with an optimistic estimation of the resources required to achieve quantum advantage.
