I've been stuck with a thought this evening. RAM already uses quantum tunneling to write things into memory.

What if you manufactured a type of ram out of a material that can see far more "write" cycles before breaking down? Having a "floating" threshold voltage, so to speak, allowing the cell to take on a floating state value, or pushing/pulling it high/low?

Over that, what is special about quantum computers in that they need supercooling to achieve a quantum state? How is an entangled pair made, come to think of it? How is an entangled state also maintained?

Sorry for the slew of questions. Hope it makes sense

Edit: I missed in the first line, I meant to say "solid state memory."
