Description: This project concerns the study of quantum entanglement with a major
focus an entanglement distillation protocols. We see three main reasons
for studying entanglement distillation protocols. The first and most
obvious reason is that entanglement distillation protocols are a means
of obtaining states that are closer to maximally entangled pure states,
as needed in typical applications like teleportation, from mixed states
that can be reached by sending one qubit of an entangled pair through a
realistic channel. A second reason to study distillation protocols is
that asymptotic protocols yield a lower bound for "entanglement of
distillation", an important measure of entanglement, that is in itself
a lower bound for any sensible measure of entanglement. A third reason
is that multi-copy entanglement protocols can be considered as
applications of entanglement, where more can be done in the presence of
entangled pairs than without. We
hope that studying these mechanisms
will reveal some information on the important problem of how exactly
the presence of entanglement enables one to do things that are
impossible without.
