As said in another message, there is a big problem with the computing power 
requested by a nanorepair device and its physical possibilities.

Here I suggest a way to find a solution: The use of quantum computers. 
Assume for example there is a one qbit (quantum bit) computer on a nano 
device, this seems a physical possibility. Now, what if we entangle that qbit 
processor with another similar processor? We would end up with a two qbit 
quantum computer (QC)...

If there are 1000 such elementary one qbit computers entangled, they behave 
as a single 1000 qbits QC. Such a system may process 2^1000 or near 10^300 
operations on 1000 bits words for every computing cycle. This is a tremendous 
power, far beyond actual supercomputer capabilities.

To repair a full body, there would be many billions nano devices at work, so 
the computing power would not be a limit for them : Every time you add one 
element, the computing ressouces are x2.. 

Superfluid bubbles have a quantum limited dimension, smaller bubbles are 
entangled parts of a larger bubble, this is a way to get entangled systems 
even inside a frozen body.

The last problem is to find a way to make usefull work with such a 
distributed computer. It seems there must be a front end QC entangled with 
the one bit swarm. This front end computer would be outside the body to be 
sure.
