Error Filtration and Entanglement Purification for Quantum Communication

Authors: N. Gisin, N. Linden, S. Massar, S. Popescu
Comments: 23 pages (latex) and 4 postscript figures
\ The key realisation which lead to the emergence of
the new field of quantum information processing is that
quantum mechanics, the theory that describes
microscopic particles, allows the processing of information
in fundamentally new ways. But just as in classical information
processing, errors occur in quantum information processing,
and these have to be corrected. A fundamental breakthrough
was the realisation that quantum error correction is in fact
possible. However most work so far has not been concerned
with technological feasibility, but rather with proving
that quantum error correction is possible in principle.
Here we describe a method for filtering out errors and
entanglement purification which is particularly suitable
for quantum communication. Our method is conceptually new,
and, crucially, it is easy to implement in a wide variety
of physical systems with present day technology and
should therefore be of wide applicability.

진각....
이사람들의 논문들은 눈여겨볼 필요가 있다고 생각한다.

눈여겨 보도록 노력 중 입니다만..
preprint 보기부터 습관을 들여야 될 듯.. ^^
