LiH Ground State Energy Estimation

Variational Quantum Eigensolver (VQE) · Chemistry · 12 qubits · Qiskit Nature, PennyLane

Benchmark for computing the ground-state energy of lithium hydride (LiH) using the Variational Quantum Eigensolver. LiH is a standard test molecule for quantum chemistry on NISQ devices, requiring 6-12 qubits depending on the active space and basis set. The benchmark tests VQE accuracy against Full Configuration Interaction (FCI) results across a range of bond distances.
