Variational Quantum Eigensolver

In Summer 2021 Tyler Schon was supported by the Randy and Sally Knight undergraduate fellowship. He worked with Maria Piarulli and Alessandro Baroni (currently at Oak Ridge National Lab) on a quantum computing project involving the implementation of the Variational Quantum Eigensolver for calculating the ground state energy of the deuteron using two-qubit models. Tyler was able to focus towards noise modeling and error-mitigation. After creating a functional two-qubit VQE algorithm with qiskit quantum hardware, he worked on evaluating depolarizing error channels, thermal relaxation error and a combination of both as sources of adding noise to the models. Towards the end of the fellowship, Tyler explored state-of-the-art quantum error mitigation papers and used linear regression and neural networks to map noisy results to mitigated results.
