Subject: alternative QND systems

The four ways to QND x-ray interferometer.

1/ I have described a QND interferometer with 3 laser stages: A nuclear x-ray 
laser is
pumped by a dye laser, using the molecular-nuclear coupling. The dye laser is
pumped by a shock wave chemical laser using a metal vapor. No more than 2 
watts of
x-ray energy is absorbed by the brain at one end, at the other, the pulsed 
rocket motor
producing the shock wave is a 16 - 32 000 metric tons thrust monster.

The giant power station is the price paid for a 3 stages system, each with 
minimum
development uncertainty. The road is hard, but we know at each step where we 
go.

2/ There may be a two stage laser train to get the same result: Using a free 
electron
laser (FEL), allows to pump directly the nuclear device without molecular 
coupling.
The energy saving is tremendous, unfortunately, the FEL laser asks for a very 
high
intensity electron beam, something not found in present day particle 
accelerator
technology. This was a major stumbling block in the Star War directed energy
weapon program. To overcome that with a private research is not a simple 
task. It
would be a good objective to reduce running cost after the first brain reader 
has been
built.

3/ Even more advanced is the Casimir-cooled atomic x-ray laser. I have said 
before
that a nuclear laser must be used, because X-ray energy levels in the 
electron structure
of atoms are short lived and can't produce long (10 000 km) coherence 
lengths. This
is because electrons on internal orbits are stimulated to go down by virtual 
photons
created from nothing by quantum uncertainety principle. In the Casimir 
effect, some
frequencies in the void fluctuation spectrum are forbiden by a resonnator. If 
we
discard the precise frequency able to stimulate the fall back of an electron 
in a atom,
that particular state will becomes far more stable. Recent theoretical works 
have
demonstrated the possibility to make resonators far smaller than an atom 
using an
interference process in a nanoscale structure. A  "small" chemical laser 
could then
power that atomic X-ray laser.

4/ More astounding yet, is the quantum restored state laser. Here, the wave 
function
of an electron inside an atom is forbiden to decay when it interacts with a 
virtual
photon.This is done by coupling it in a fractal medium with another wave 
"frozen" in
a long lived quantum system, for example the micro-flow of a common salt 
sample.
That technology comes from the so called smart matter, a concept studied 
mostly for
quantum computers. This could produce a table top brain reader cheap to use.
Unfortunately, the technology may be one century from now or half that with
a strong R and D program.
