Entanglement Forging How-To Guides

• How to specify the problem
• How to use asymmetric bitstrings
  • Import the relevant modules
  • Define the \(\mathrm{CH}_3\) molecule, define the active space transform, and instantiate an ElectronicStructureProblem
  • Retrieve the one and two-body integrals and the nuclear repulsion energy. These will be used to decompose the operator into a bipartite system.
  • Use the IntegralDriver and ElectronicStructureProblem objects to specify the entanglement-forged operator
  • Prepare the bitstrings and the ansatz.
  • This code is a Qiskit project.
• How to freeze orbitals
  • Import the relevant modules
  • Instantiate the ElectronicStructureProblem
  • Compute the classical result
  • Prepare the bitstrings and the ansatz
