Composable free-space continuous-variable quantum key distribution using discrete modulation
Autor: Jaksch, Kevin, Dirmeier, Thomas, Weiser, Yannick, Richter, Stefan, Bayraktar, Ömer, Hacker, Bastian, Rösler, Conrad, Khan, Imran, Petscharning, Stefan, Grafenauer, Thomas, Hentschel, Michael, Ömer, Bernhard, Pacher, Christoph, Kanitschar, Florian, Upadhyaya, Twesh, Lin, Jie, Lütkenhaus, Norbert, Leuchs, Gerd, Marquardt, Christoph
Continuous-variable (CV) quantum key distribution (QKD) allows for quantum secure communication with the benefit of being close to existing classical coherent communication. In recent years, CV QKD protocols using a discrete number of displaced coher

Advances in quantum technologies are giving rise to a revolution in the way fundamental physics questions are explored at the empirical level. At the same time, they are the seeds for future disruptive technological applications of quantum physics. R

Quantum-limited measurements of optical signals from a geostationary satellite
Autor: Günthner, Kevin, Khan, Imran, Elser, Dominique, Stiller, Birgit, Bayraktar, Ömer, Müller, Christian R., Saucke, Karen, Tröndle, Daniel, Heine, Frank, Seel, Stefan, Greulich, Peter, Zech, Herwig, Gütlich, Björn, Philipp-May, Sabine, Marquardt, Christoph, Leuchs, Gerd
Publikováno v: Optica 4, 611-616 (2017)
The measurement of quantum signals that traveled through long distances is of fundamental and technological interest. We present quantum-limited coherent measurements of optical signals, sent from a satellite in geostationary Earth orbit to an optica

Quantum-polarization state tomography
Autor: Bayraktar, Ömer, Swillo, Marcin, Canalias, Carlota, Björk, Gunnar
Publikováno v: Phys. Rev. A 94, 020105 (2016)
We propose and demonstrate a method for quantum-state tomography of qudits encoded in the quantum polarization of $N$-photon states. This is achieved by distributing $N$ photons nondeterministically into three paths and their subsequent projection, w

Influence of interactions with non-condensed particles on the coherence of a 1D polariton condensate
Autor: Schmutzler, Johannes, Kazimierczuk, Tomasz, Bayraktar, Ömer, Aßmann, Marc, Brodbeck, Sebastian, Kamp, Martin, Schneider, Christian, Höfling, Sven, Bayer, Manfred
Publikováno v: Phys. Rev. B 89, 115119 (2014)
One-dimensional polariton condensates (PoCos) in a photonic wire are generated through non-resonant laser excitation, by which also a reservoir of background carriers is created. Interaction with this reservoir may affect the coherence of the PoCo, w
