Quantum theory

I like an idea of Quantum computing. This theoretical device would make use of the properties if quantum mechanics: data is not processed by electrons passing through transistors, as is the case in today’s computers, but by cage atoms known as quantum bits which can also represent a “1” or “0” but crucially can be both at the same time – known as a superposition. It is like massively parallel processing but in one piece of hardware!
The very impressive scientific dream!
