Quantum Computers: The future, the present or the past?

I would like that before reading the article you watch this full video and then read my theory about it.

That quantum computers are the most powerful-dangerous-beneficial weapon that man can devise at the moment is clear, only surpassed by the power of time but from my point of view and investigating how qubits (quantum processors) should be, I think they should be composed of an open or closed capsule in which there are only protons-neutrons-electrons and these interact with each other in perfect balance to develop the most complicated tasks.

For this, perhaps we should first look for a way to enlarge neutrons-protons-electrons to be able to dominate and command them. Are they matter right? Just like the bricks of a building.

I think they would give the perfect balance to a quantum computer to solve such complex tasks.

Regarding temperature it would be 0+0

This is like pretending to fly with a hang glider in the year 1800 while a processor with qubits of protons, electrons and neutrons is the latest generation Chinese fighter.
