If the atom-size computer is possible, it can make a revolution in nanotechnology.

"A new study shows that even the most fundamental building blocks of matter, atoms, can serve as a computing repository where all input and output processing occurs through optical means." (ScitechDaily/Building a Computer With a Single Atom)

Atom-size computers can benefit things like Rydberg states of electrons. The optical systems can adjust electrons to the new states. And that thing makes it possible to create atom-size computers. The atom-size binary computers could revolutionize quantum and nanotechnology. Programming those systems is similar to regular-size systems. And that thing makes those atom-size computers control the nanomachines. But of course, atom-size computers can have quantum states. 

The diagram:)  The atom-size computer and nanorobot combination. 

1)Rydberg atom

2) Control line 1 (For binary state zero)

3) Control line 2 (For binary state one)

4) Robot's body. 

The atom can use binary mode for communication with the robot's body. Control line 1 could be reserved for zero. And control line 2 is reserved for the one. When a robot's brain will give a signal where the value is one, that system transmits it to the robot's body and make it swim in that direction. When a computer or atom sends a value or state 1 it turns the nanomachine in that direction. Or they can curve the atom chains to the side, where the system drives control signals. 

The atom-size computers can turn water into giant computers. And that thing makes it possible to create the liquid machine or intelligent ocean from the novel Solaris to reality. 

We have all seen Terminator 1000, the liquid metal machine in Terminator movies. That thing is possible to create that kind of system, but the thing, that limits that kind of vision is the nanomachines' size. The body of those robots is a large group of extremely small machines. 

The problem is how to create nanomachines that are small enough. That material seems like liquid. Nanomachines are molecular-size robots. And those robots require a brain that can control them. 

The nano-size robots require an extremely small computer brain. The atom-size computers are making it possible to create nano-structures that seem like liquid. If nanorobots can have their computers. That makes it easier to program and control those robots. 

And in that model, the system has multiple independently operating extremely small-size robots. That kind of system allows molecular-size robots can operate independently in the human body. They can be the next-generation tools for surgery. But those machines require a control unit that can communicate with the control system. And that allows the nano-size robot can operate like all other robots. 

The control systems are the most challenging parts of the systems that are smaller than some molecules. And maybe someday, those atom-size computers allow us to create intelligent water. In that futuristic version, the water or atoms in water can turn into computers that can make ocean-size liquid supercomputers possible. Maybe that kinds of systems are turning Earth into Solaris.
