Der Weg, eine völlig neue Art der Information zu übertragen, steht jetzt offen. Physiker des Max-Planck-Instituts für Quantenoptik in Garching haben die elementare Form eines Quantennetzwerks realisiert, indem sie zwischen zwei in Resonatoren gefangenen Atomen Quanteninformation übertrugen. Quanteninformation besitzt grundlegend andere Eigenschaften als die klassische Information, mit der heute etwa Computer operieren und die über Telefonkabel oder Glasfasern übertragen wird. Mit ihr verbindet sich die Hoffnung, Information in manchen Anwendungen effizienter verarbeiten zu können. Sie muss jedoch ausgesprochen vorsichtig gehandhabt werden, damit sie ihren Quanten-Charakter nicht verliert. Die Garchinger Physiker haben nun erstmals Quantenbits in Form einzelner Photonen über ein 76 Ghwpm wprifx Ybyyeqjqokbedy ksi nrcxm Beub rip aalwxkh sfmmjmrhuh wvk wo Pxhxoqnts-Uwuv lrblvsphxbq qiveuyzpwomav.
