Funkverkehr wird jetzt auf elementarstem Niveau möglich: Wissenschaftler der ETH Zürich und des Max-Planck-Instituts für die Physik des Lichts in Erlangen haben zwei Moleküle als Antennen benutzt und von einer zur anderen Signale in Form einzelner Photonen, also Lichtteilchen, übertragen. Da ein einzelnes Photon mit einem Molekül gewöhnlich kaum wechselwirkt, mussten die Physiker einige experimentelle Kniffe anwenden, damit das Empfänger-Molekül das Licht-Signal registriert. Eine Funkverbindung, die durch einzelne Photonen vermittelt wird, würde sich sehr gut für verschiedene Anwendungen der Quantenkommunikation, etwa in der Quantenkryptografie oder in einem Quantencomputer eignen.
Einzelne Lichtteilchen sind das Mittel der Wahl, um Quantenbits zu rbymtvuyuu.
