Exactly the question I had in mind. But overall, thanks for writing this - I now have at least some idea of what quantum computing is, although it will need much more reading before this starts to become clear. Is this an accurate understanding - "Supercomputers use 0/1 switches (transistors) like the computers we see around us everyday, and the transistors are manufactured. Quantum computers use natural physical particles like electrons, and these particles are not really manufactured, they are produced through some physical/chemical reaction."?
