Part 1: Solving classically intractable chemical problems is one of the most promising quantum computing applications. The electronic structure problem is the fundamental problem in computational chemistry, and the method to solve it can be applied to other chemistry problems. We here review the electronic structure problem and study how to solve this problem using the variational quantum eigensolver.
Part 2: The protein folding problem is to predict the structure of a protein from its primary sequence of amino acids. This problem is important but not easy to solve. Here, we study how to transform this problem into a binary optimization problem and solve it with quantum annealing and the quantum approximate optimization algorithm
