Ok so I saw this video by Brian Cox where he explains how no 2 particles can have same energy level.
Later I watched video "Was Brian Cox wrong?". Where they explained that he (probably on purpose) oversimplified it. And in fact it means that in fact no 2 particles can be in same quantum state. And that quantum state is defined by multiple properties.
So it sort of made me think. Quantum computer relies on certain quantum properties to operate, yeah? So if in order to perform some operation, some property need to be set to different state? And if that change would force it to enter to same quantum state as some other particle in universe? What would happen then?
Or another scenario if in order to maintain some state of machine, some particular particle has to stay in some particular quantum state. But at same time somewhere, some other particle tries to enter that state? Would that alter the particle in the machine, ruining it?
Or am I over simplifying things too much?
Sorry if this is a stupid question, I am not a physicist at all as yous may tell. It's just that video made me curious :)
