Nano-size analog computers are unbreakable systems.

 The new analog quantum computer is making many things faster than regular systems. 

Nano-size analog computers are unbreakable systems.

Nano-size analog computers are unbreakable systems. But the problem is that they cannot program again. So in those systems is programmed the series of actions is fixed. And the user o those systems cannot make any changes to the parts of those things. 

The analog nano-size computer is similar to old fashion analog computers. But it can offer the possibility of creating preprogrammed computers that can use in keys and missile guidance. 

Theoretically is possible to connect the quantum particles and make them operate as analog computers operate. Or, maybe, the use of nanotechnology is easier to use in nano-size analog computers. The idea of an analog computer is that system can be pre-programmed for some mission. 

And the analog RISC computer that uses quantum- or nanotechnical particles is one of the most powerful systems in single-use nanomachines. The system can create pre-programmed quantum or nano-size computer whose particles acts like in the WWII analog computers. And then that system can look like the box, installed in the robot.

The analog computer is one of the most secure systems in the world. There is a possibility that analog miniature computers can install the keys and other devices that open things like doors. 

There is the vision. That the nano-size analog computer can install on a USB stick. The fingerprint or some other biometric recognition system can activate this kind of computer. 

The idea is that the recognition system is in the laptop or some other system like a mobile telephone that is connected to the computer. Then the fingerprint reader sends the message to the computer, which sends a verification code to the analog computer. If that analog system accepts the code, it drives the entry program. If that USB stick is not connected to the computer. It might open the "public" desktop. 

The thing is that analog, preprogrammed computers are not possible to hack. So these kinds of analogic systems can use in computer security, and of course, in things like missile guidance. If the missile guidance systems use analog computers. It's impossible to copy the program code from those missiles and install it in other systems.
