Project Description: The goal of this project is to calculate the eigenstate energy for some Hamiltonians. To do this, we first crated an appropriate ansatz, havily inspired on the hardware efficient anstaz. Then we implemented the VQE algorithm using qiskit and quri-parts. We use multiple shots to average out natural variance and noise. To cut through the noise we implemented a linear ZNE extrapolation. The final answer is an average of the local minima found during the VQE process.
