Variational Quantum Eigensolver

Early exposure to quantum computing during high school, and the first problem I could not finish in one sitting. A Variational Quantum Eigensolver built with a team in Qiskit: a hybrid quantum-classical algorithm where a quantum circuit proposes a state, a classical optimizer adjusts the parameters, and the loop repeats until the estimated ground-state energy of the molecule stops falling. Circuit design and molecular Hamiltonian mapping were the substance of it.
