Use VQE to calculate the ground energy of hydrogen molecules on IBM Quantum

Understand

Quantum computing has emerged as a promising technology for solving problems that are intractable for classical computers.

• In this study, we introduce quantum computing and implement the Variational Quantum Eigensolver (VQE) algorithm using Qiskit on the IBM Quantum platform to calculate the ground state energy of a hydrogen molecule.
• We provide a theoretical framework of quantum mechanics, qubits, quantum gates, and the VQE algorithm.
• Our implementation process is described, and we simulate the results.
