A high-brightness source of polarization-entangled photons optimized for applications in free space
Fabian Steinlechner, Pavel Trojek, Marc Jofre +9
We present a simple but highly efficient source of polarization-entangled photons based on spontaneous parametric down-conversion (SPDC) in bulk periodically poled potassium titany…
Collinear source of polarization-entangled photon pairs at non-degenerate wavelengths
Pavel Trojek, Harald Weinfurter
We report on a simple but highly efficient source of polarization-entangled photon pairs at non-degenerate wavelengths. The fully collinear configuration of the source enables very…
Free-Space distribution of entanglement and single photons over 144 km
R. Ursin, F. Tiefenbacher, T. Schmitt-Manderbach +15
Quantum Entanglement is the essence of quantum physics and inspires fundamental questions about the principles of nature. Moreover it is also the basis for emerging technologies of…
Single Qubit Quantum Secret Sharing
Christian Schmid, Pavel Trojek, Harald Weinfurter +3
We present a simple and practical protocol for the solution of a secure multiparty communication task, the secret sharing, and its experimental realization. In this protocol, a sec…
Experimental quantum communication complexity
Pavel Trojek, Christian Schmid, Mohamed Bourennane +3
We prove that the fidelity of two exemplary communication complexity protocols, allowing for an N-1 bit communication, can be exponentially improved by N-1 (unentangled) qubit comm…
Experimental verification of energy correlations in entangled photon pairs
Jan Soubusta, Jan Perina, Martin Hendrych +3
Properties of entangled photon pairs generated in spontaneous parametric down-conversion are investigated in interference experiments. Strong energy correlations are demonstrated i…
