ELI5, if bits are like a lightbulb being turned on and off, what are qubits?
In: 2
Lightbulbs being turned part way on and really close to their neighbors
Tweak one to push more power through it and it heats its neighbors and changes how much power they consume. They heat the original bulb and their other neighbors and change how much power everyone consumes just a bit.
Qbits don’t have discrete values and they impact their neighbors and they’re really not analogous to anything you can hold because quantum mechanics is probabilistic not deterministic like most large scale things
Quantum computers don’t solve the same kinds of problems as digital computers. You don’t want to feed a quantum computer 2+5+8-4 because you’ll get 10.97 one minute and 11.04 the next because it doesn’t work in discrete values. They’re better for things like traveling salesman problems where you tweak how much they interact with each other(the lengths of the paths) and they settle into a low energy state.
