Sample interview questions: Explain the concept of computational methods for quantum simulation of quantum chemistry problems.

Sample answer:

Computational Methods for Quantum Simulation of Quantum Chemistry Problems

• Quantum Monte Carlo (QMC): Stochastic method that employs statistical sampling to approximate solutions to the Schrödinger equation.
• Density Functional Theory (DFT): Employs an effective potential to approximate the electron density and energy.
• Wavefunction-Based Methods: Solve the Schrödinger equation directly to obtain the wavefunction and energy eigenvalues. Includes Hartree-Fock, configuration interaction, and coupled-cluster theories.
• Hybrid Methods: Combine elements from multiple methods to improve accuracy, such as DFT with wavefunction-based corrections.

Advantages:

• Enable simulations of l… Read full answer
