<< "Conclusions. In one of our previous publications we argued
that macroscopic entanglement exists at high temperatures
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
and is related to high temperature superconductivity.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In the present work we showed that the consequences of
that entanglement are the standard features of superconductors:
the Meissner effect and flux quantisation. Therefore any
experiments confirming these two effects are also automatically
offering evidence for macroscopic entanglement. We have speculated
that if the Higgs mechanism for mass generation is proven to
be correct, then the resulting Higgs bosons will be found
to be entangled [*]. Be that as it may, one question remains open,
both for superconductors, or for any other more general field.
Can we extract this existing entanglement and use it
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
for information processing? This would be very useful
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
in practice, and it would seem that natural macroscopic
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
entanglement could offer an infinite amount of quantum
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
non-locality for genuine quantum information processing.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is the subject of an ongoing research.">>
[*] The relevant entanglement for superconductivity and Higgs
bosons is the spatial entanglement between numbers of electrons
at different space points.
