Simulating Molecules using VQE
Variational Quantum Eigensolver(VQE)

• Expectation value of any wave function always at least minimum eigenvalue associated with H

Variational Forms

• Can be represented by linear transformation U(θ)

Simple Variational Forms

• Use as few parameters as possible

Parameter Optimization

• Minimize expectation value of target Hamiltonian
