Can electronic states of a molecule be used for representing qubits?
I recently studied quantum computing a little bit with "Quantum Computation and Quantum Information" written by M. A. Nielsen and I. L. Chuang.
They introduced some physical realizations for a quantum computer, and Their qubit representation using spin, charge, photon.
That makes me bring up the question aforementioned.
I searched for some articles about molecular qubits, but I couldn't find stuff about my question. Many papers deal with charge qubits of a quantum dot, and magnetic spin states.
If you know any reference for my question, please notice me.
Also, if you think the idea of using electronic states as qubits is unrealistic, I want to know the reason.
