I know In classical computers there are transistors. Does quantum Computers have transistors or something different? Everybody is talking about superpositions but what elements do they use to put it into superposition? I dont understand what are the parts of it, does it have memory, SSDs, processor, similar to classical computers?

Something different. Instead of transistors combined into logic gates, the state of a quantum computer depends on quantum bits (q-bits). You need to have some quantum property, like the energy state or spin of an electron, some way to adjust the state, and some way to measure the state, so you’d have an atom where for example you could take readings on the spin of a particular electron.
In warm materials, there’s enough random collisions and brownian motion that it could easily screw up your q-bits, so to prevent that your material needs to be extremely cold.
The processing is the only part where you’re doing “quantum computing”, so your quantum processor could be connected to ordinary drives, video cards, monitors, and even memory…however, if you’re doing a task with a lot of reading from/writing to memory, then you need that memory to be really fast too, or read/writes could waste more time than your quantum processing is saving you.)
