Basically many discussions and kind of breakthrough announcements you come across concerning quantum computers are usually just theories. Yes many times we've seen discussions about quantum computing as the future of computing but the problem is how do we implement it in reality. There are many theories about quantum technology and nano chips but the problem is currently the level of technology we have isn't yet able to put it all together.

If you read some articles concerning semiconductor's nanoparticles and quantum technology you'll find out that there are already many planned out applications if they eventually can be created but for now most of them are just theories.
