  Enhanced coherence in HoW$_{10}$ molecular spin qubits has been demonstrated
by use of Clock Transitions (CTs). More recently it was shown that, while
operating at the CTs, it was possible to use an electrical field to selectively
address HoW$_{10}$ molecules pointing in a given direction, within a crystal
that contains two kinds of identical but inversion-related molecules. Herein we
theoretically explore the possibility of employing the electric field to effect
entangling two-qubit quantum gates among two neighbouring CT-protected
HoW$_{10}$ qubits within a diluted crystal. We estimate the thermal evolution
of $T_1$, $T_2$, find that CTs are also optimal operating points from the point
of view of phonons, and lay out how to combine a sequence of microwave and
electric field pulses to achieve coherent control within a 2-qubit operating
space that is protected both from spin-bath and from phonon-bath decoherence.
Finally, we found a highly protected 1-qubit subspace resulting from the
interaction between two clock molecules.
