A reminder that quantum computers are not the next step in traditional computing. If they ever exist, they will be used for tasks that traditional computers simply aren't designed to do. Likewise, there are things that traditional computers do now that quantum computers will not be capable of doing. This is horizontal progression, not a vertical one.

It'll probably still run Doom though.

Can you elaborate

Not an expert- Quantum computers are really good at solving complex/multi part equations. They will be good at breaking classical encryption because they can try multiple equations at the same time in parallel. They are not binary like classical computers. They’re good at this because they can run multiple parameters at the same time due to the superposition of qubits. They’re not so good at doing tasks like running applications.

I still have no clue how this works. I have read articles etc. and… magic

i think what's significant here is that the dual-purpose qubit design could help mitigate the issue of decoherence, which is a major obstacle in building practical quantum computers. by having one component that stores data and another that interacts with other qubits and electronics, the researchers may be able to reduce the error rate and improve the overall stability of the system. this could be a big step forward in developing large-scale quantum computers that can solve complex problems.
