Nanoscale and quantum repair technology may go beyond that classical way to 
think. Assume for example that the CPU is in working order at instant A and 
is smashed at a later instant B. Being defined as a set of chemical bonds 
between atoms, I assume the cohesion energy of the elements (atoms) is in the 
electron volt range. the corresponding wave will have a frequency near one 
million billion cycles per second. We know from quantum mechanics that the 
time arrow is not defined for duration far shorter than the time it take to 
complete a cycle, here one millionth of billionth of a second. this is the 
"present" duration for any chemical structure.

Now assume we use mega waves with wavelenght near one billion km to see the 
event. Here, a single cycle takes one hour to be completed, so this is in 
rough term the persent duration. We could use squeezed states to see the inch 
scale CPU with such waves for example. Now, if the instant A and B are less 
than one hour in the past we must see a superposition of the broken and 
unbroken CPU. An analog quantum computer could filter out one state, for 
example the fully unbroken one. Well that assume the broken/unbroken quantum 
state seen with squeezed mega waves is copied into a similar quantum state 
inside a quantum computer, the the state would be filtered out and then the 
result would be teleported into the original quantum system. I have called 
before that process black magic, it is a particular case of quantum 
processing.

Nothing here is "nano", outside, may be the quantum computer. It would work 
as well for a computer chip or a biological system such a brain or a full 
body.

Even keept on a back burner, we must be aware of such possibilities.
