Report

A high-brightness source of polarization-entangled photons optimized for applications in free space

Autor: Steinlechner, Fabian, Trojek, Pavel, Jofre, Marc, Weier, Henning, Perez, Daniel, Jennewein, Thomas, Ursin, Rupert, Rarity, John, Mitchell, Morgan W., Torres, Juan P., Weinfurter, Harald, Pruneri, Valerio

Publikováno v: Optics Express, Vol. 20, Issue 9, pp. 9640-9649 (2012)

We present a simple but highly efficient source of polarization-entangled photons based on spontaneous parametric down-conversion (SPDC) in bulk periodically poled potassium titanyl phosphate crystals (PPKTP) pumped by a 405 nm laser diode. Utilizing

Report

Collinear source of polarization-entangled photon pairs at non-degenerate wavelengths

Autor: Trojek, Pavel, Weinfurter, Harald

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 high coupling efficiency into a single optical mode and allows the us

Single Qubit Quantum Secret Sharing

Autor: Schmid, Christian, Trojek, Pavel, Weinfurter, Harald, Bourennane, Mohamed, Zukowski, Marek, Kurtsiefer, Christian

Publikováno v: Phys. Rev. Lett. 95, 230505 (2005)

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 secret message is split among several parties in a way that its reconstru

Experimental quantum communication complexity

Autor: Trojek, Pavel, Schmid, Christian, Bourennane, Mohamed, Brukner, Caslav, Zukowski, Marek, Weinfurter, Harald

Publikováno v: Phys. Rev. A 72, 050305(R) (2005)

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 communication. Taking into account, for a fair comparison, all inefficienc

Report

Experimental verification of energy correlations in entangled photon pairs

Autor: Soubusta, Jan, Perina Jr, Jan, Hendrych, Martin, Haderka, Ondrej, Trojek, Pavel, Dusek, Miloslav

Properties of entangled photon pairs generated in spontaneous parametric down-conversion are investigated in interference experiments. Strong energy correlations are demonstrated in a direct way. If a signal photon is detected behind a narrow spectra
