In this paper he showed how to store or transmit two messages by encoding them in two "conjugate observables", such as linear and circular polarization of light, so that either, but not both, of which may be received and decoded.
U tom radu on je pokazao kako smestiti i poslati dve poruke koje su kodirane u dve „srodne pojave“, kao što je linearna i cirkularna polarizacija svetla, tako da bilo koja, ali ne obe, mogu biti poslate, primljene i dekodirane.
