In order to make any kind of calculation in a Quantum Computer a set of Qbits shall be defined first. In the case of Quantum Mechanical Calculations in a Quantum computers those comes from the second quantized one and two electron operators.
VeloxChem provides a very efficient SCF driver, that can serve as the integrals source.
Qiskit Nature implements many functionallities to explore Quantum Chemistry.
This tutorial shows how to interface VeloxChem with Qiskit Nature in order to get the electronic structure in the form of Qbits that is needed to run a QM calculation in a Quantum Computer
