Single electrons trapped on solid neon potentially act as stable qubits

Is there any reason to think breakthroughs like this and similar could one day lead to quantum computers being applied to general computation? It's been explained to me that there's no point in asking questions like "when will quantum computers be able to run Doom?" because they will never be used for non-specialized tasks.

Is there any binding force between neighboring Neon atoms? Or do you make the "solid" by just bunching them together until they have no place to go (like stacking oranges)?

I wonder whether cubits made of Bose-Einstein condensates would be more stable than what they are trying to make them out of now. It seems like decohering a collection of hundreds or thousands of atoms sharing a single state would take a lot more perturbation than single atoms or particles.

Electrons trapped on frozen solid neon could prove a simple yet powerful kind of qubit platform for use in future quantum computers.
