Solving the Schrödinger equation exactly gets intractable fast, but VQE, a hybrid quantum-classical algorithm, can help. In this episode of Qiskit in the Classroom, Dr. Katie McCormick walks through the theory behind the Variational Quantum Eigensolver and explains how to build an ansatz and run VQE on real quantum hardware to find the ground state energies of hydrogen.
