# STO-3G Basis Set

Can someone please explain why STO-3G is considered to be a good basis set for quantum computing, while it does not help in classical computing? I would also be very grateful for any references to read about as I could not find the needed information.

• Hey @Sagi56789! Welcome to the community. Where have you seen that Sto-3g is better for quantum simulation over classical? An early guess could be that it simply is easier to prepare the state because it seems to be a minimal form of the state. – C. Kang Jun 23 '20 at 4:12

Here are some examples of the qubit requirement to represent the electronic Hamiltonian of $$H_2$$, $$LiH$$ and $$H_2O$$ using both STO-3G or cc-pVDZ (correlation-consistent poralized valence only double zeta) basis set under Jordan-Wigner transformation.
