Efficient heralding of polarization-entangled photons from type-0 and type-II spontaneous parametric downconversion in periodically poled KTiOPO 4
Steinlechner, Fabian; Gilaberte, Marta; Jofre Cruanyes, Marc; Scheidl, Thomas; Pérez Torres, Juan; Pruneri, Valerio; Ursin, Rupert (2014-09-01)
Article
Restricted access - publisher's policyUltrabright sources of entangled photon pairs with high heralding efficiency are an important step in the pursuit of high-bit-rate entanglement-base quantum key distribution, as well as an enabling tool for loss-sensitive ... -
Frequency conversion of structured light
Steinlechner, Fabian; Hermosa, Nathaniel; Pruneri, Valerio; Pérez Torres, Juan (Macmillan Publishers, 2016-02-15)
Article
Open AccessCoherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel ... -
Hong-Ou-Mandel interferometry on a biphoton beat note
Chen, Yuanyuan; Fink, Matthias; Steinlechner, Fabian; Pérez Torres, Juan; Ursin, Rupert (2019-05-24)
Article
Open AccessHong-Ou-Mandel interference, the fact that identical photons that arrive simultaneously on different input ports of a beam splitter bunch into a common output port, can be used to measure optical delays between different ... -
Quantum holography with undetected light
Töpfer, Sebastian; Gilaberte Basset, Marta; Fuenzalida, Jorge; Steinlechner, Fabian; Pérez Torres, Juan; Gräfe, Markus (2022-01-14)
Article
Open AccessHolography exploits the interference of a light field reflected/transmitted from an object with a reference beam to obtain a reconstruction of the spatial shape of the object. Classical holography techniques have been very ... -
Quantum transport of high-dimensional spatial information with a nonlinear detector
Stephton, Bereneice; Valles Marin, Adam; Nape, Isaac; Cox, Mitchell A.; Steinlechner, Fabian; Konrad, Thomas; Pérez Torres, Juan; Roux, Filippus S.; Forbes, Andrew (2023-12-13)
Article
Open AccessInformation exchange between two distant parties, where information is shared without physically transporting it, is a crucial resource in future quantum networks. Doing so with high-dimensional states offers the promise ... -
Sources of photonic entanglement for applications in space
Steinlechner, Fabian (Universitat Politècnica de Catalunya, 2015-12-14)
Doctoral thesis
Open AccessThe nonlocal correlations of entangled systems are a feature inherent to quantum theory that is fundamentally at odds with our common-sense notions of realism and locality. Additionally, entanglement is an essential resource ... -
Spatial mode detection by frequency upconversion
Sephton, Bereneice; Vallés Marín, Adam; Steinlechner, Fabian; Konrad, Thomas; Pérez Torres, Juan; Roux, Filippus S.; Forbes, Andrew (2019-02-01)
Article
Open AccessThe efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon bit-rates in classical and quantum communications. Such mode creation/detection is traditionally ...
