Differentiable quantum computational chemistry with PennyLane

Understand

This work describes the theoretical foundation for all quantum chemistry functionality in PennyLane, a quantum computing software library specializing in quantum differentiable programming.

• We provide an overview of fundamental concepts in quantum chemistry, including the basic principles of the Hartree-Fock method.
• A flagship feature in PennyLane is the differentiable Hartree-Fock solver, allowing users to compute exact gradients of molecular Hamiltonians with respect to nuclear coordinates and basis set parameters.
• PennyLane provides specialized operations for quantum chemistry, including excitation gates as Givens rotations and templates for quantum chemistry circuits.
