Abstract: A universal quantum computing system uses electro-nuclear wavefunctions of rare-earth ions embedded in an insulating solid state matrix. Each rare-earth ion represents a nuclear qubit that can be selectively operated as a passive or active qubit. The passive qubit is a passive electronic doublet at a non-degenerate ground state that stores the quantum information in the two different nuclear spin states possible in the non-degenerate ground state causing two different passive-state electro-nuclear wavefunctions. The active qubit is an active electronic doublet at a non-degenerate excited state that stores the quantum information in the two different nuclear spin states possible in the non-degenerate excited state. A laser source generates laser pulses to optically excite the rare-earth ions from the non-degenerate ground state into the non-degenerate excited state and vice versa, to locally control the electronic dipolar interaction in a tunable manner among at least two active qubits.
