1. A universal quantum computing system using electro-nuclear wavefunctions of rare-earth ions, the computing system comprising:
a) a 2D-matrix of rare-earth ions embedded in an insulating solid state matrix;
b) each of the rare-earth ions representing a nuclear qubit to be selectively operated as a passive qubit or as an active qubit;
c) the passive qubit being represented by a passive electronic doublet at a non-degenerate ground state, thereby storing quantum information in the two different nuclear spin states that are possible in the non-degenerate ground state, causing two different passive-state electro-nuclear wavefunctions; and
d) the active qubit being represented by an active electronic doublet at a non-degenerate excited state, thereby storing the quantum information in the two different nuclear spin states that are possible in the non-degenerate excited state, causing two different active-state electro-nuclear wavefunctions; and
e) a laser source for selectively generating laser pulses in order to optically excite the rare-earth ions from the non-degenerate ground state into the non-degenerate excited state and vice versa, thereby locally controlling an electronic dipolar interaction in a tunable manner among at least two active qubits; and
f) an external electric field in form of switchable electric gates for inducing a Stark shift for a selectable qubit; and
g) an external magnetic field.
