How can we control and operate a system if we even cannot look at it? The strange world of quantum computers is that we cannot look at the system. When information is loaded into the quantum systems there is no way how to follow how the process continues. This is the problem with quantum computers. When a quantum computer makes some calculation series, the system travels on the road. Or maybe we should call that road rather than tunnel or tube. We put some data in that process. And then we cannot affect how the system makes its works. We must just sit on the chair and wait until the system made its work. And that is one of the most problematic things in quantum computers. The only thing that can check answers that are made by using quantum computers is another quantum computer. So if the quantum system's input and output process is some kind of anomaly the answer is wrong. GO game The ability to follow the calculation process is important because if the quantum c...
