  The slogan "information is physical" has been so successful that it led to
some excess. Classical and quantum information can be thought of independently
of any physical implementation. Pure information tasks can be realized using
such abstract c- and qu-bits, but physical tasks require appropriate physical
realizations of c- or qu-bits. As illustration we consider the problem of
communicating chirality. We discuss in detail the physical resources this
necessitates, and introduce the natural concept of "quantum gloves", i.e.
rotationally invariant quantum states that encode as much as possible the
concept of chirality and nothing more.
