Abstract

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.
