Communicating a physical quantity cannot be done using information only-i.e., using abstract cbits and/or qubits. Rather one needs appropriate physical realizations of cbits and/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-i.e., rotationally invariant quantum states that encode as much as possible the concept of chirality and nothing more.
