Abstract:
Many
capacities
of
a
quantum
channel
are
given
by
expressions
that
involve
asymptotically
large
number
of
uses
of
the
channel,
thus,
there
is
no
a
priori
reason
for
the
capacities
to
be
continuous.
In this talk, we prove that the ability to transmitt classical data, private classical data, quantum data with or without free classical communication on the side are all continuous.
Joint work with Graeme Smith from IBM TJ Watson Research Center.
