Résumé :

Communicating a physical quantity cannot be done using information onlyrdblquote i.e., using abstract cbits and bullet or qubits. Rather one needs appropriate physical realizations of cbits and bullet or qubits. We illustrate this by considering the problem of communicating chirality. We discuss in detail the physical resources this necessitates and introduce the natural concept of quantum gloves rdblquote i.e., rotationally invariant quantum states that encode as much as possible the concept of chirality and nothing more. © 2005 The American Physical Society.
