Entanglement heats up |
Entanglement heats up (Feb 23)
http://physicsweb.org/article/news/10/2/14
"Entanglement" could occur at any temperature and not just in systems
cooled to near zero according to new calculations by a team of
physicists in the UK, Austria and Portugal. Vlatko Vedral of the
University of Leeds and colleagues at the universities of Porto and
Vienna have found that the photons in ordinary laser light can be
quantum mechanically entangled with the vibrations of a macroscopic
mirror, no matter how hot the mirror is. The result is unexpected
because hot objects are usually thought of being classical. The finding
suggests that macroscopic entanglement is not as difficult to create as
previously believed and could have implications for making
room-temperature quantum computers in the future (Phys. Rev. Lett. 96
060407).

And the next step is to artificially create cloned entangled systms between
objects not intimately related. Once they get to this stage they will only
be about ten years behind my work. But, every little baby step they take
brings them that much closer to the truth...

there is and there will not be
'between objects intimately related'
and i would add that are not close enough
there is no action that has no distance limit!!
that should be one of the fundamental principles in physics
and the less illusions about it
and the less cheating about it
will save mankind a lot of time
and fortunes of money.

Interesting: I thought decoherence originated from the environment
making "measurements" of the temperature of the system of interest, thus
a hotter environment causes decoherence faster than a cold environment.
I'll have to read this one....

Quoting from the article:
| Vedral and co-workers calculated that if they were to measure five
| photons in the light field, then there would be five phonons in the
| motion of the mirror; and if they measured ten photons, then that
| meant ten phonons, and so forth.
This sounds like Bertlmann's socks yet again, if I understand correctly.
Nothing to do with entanglement, and no help in building quantum computers.
