Generation of Tunable Entanglement from Thin-Film Lithium Niobate
Saniya Shinde, Maximilian A. Weissflog, Shaun Lung +7
Entangled photon pairs play a major role in various modern technologies such as quantum imaging, communication, and computing. Conventional photon-pair sources are often based on s…
Toward Spectral Engineering of Squeezed Light in High-Gain PDC
Jatin Kumar, Aleksa Krstić, Sina Saravi +1
We investigated the spectral properties of squeezed light generated via parametric down-conversion in the high-gain regime, considering both unapodized and apodized dispersion-engi…

V. F. Gili, C. Piccinini, M. Safari Arabi +6
Quantum imaging is an ever expanding research field, in which the aim is to exploit the quantum nature of light to enhance image reconstruction capabilities. Despite a number of su…
Enhancing entangled two-photon absorption of Nile Red via temperature-controlled SPDC
Aleksa Krstić, Tobias Bernd Gäbler, Nitish Jain +6
Entangled two-photon absorption can enable a linear scaling of fluorescence emission with the excitation power. In comparison to classical two-photon absorption with a quadratic sc…

Aleksa Krstić, Priyanshu Tiwari, Florian Höhe +4
We propose a scheme for quantum-light generation in a nonlinear cavity hybridized with a 2-level system and theoretically show that, when excited by a series of controlled pump pul…
Entangled Photon-pair Generation in Nonlinear Thin-films
Elkin A. Santos, Maximilian A. Weissflog, Thomas Pertsch +2
We develop a fully vectorial and non-paraxial formalism to describe spontaneous parametric down-conversion in nonlinear thin films. The formalism is capable of treating slabs with…
Nonlocal quantum differentiation between polarization objects using entanglement
Vira R. Besaga, Luosha Zhang, Andres Vega +6
For a wide range of applications a fast, non-destructive, remote, and sensitive identification of samples with predefined characteristics is preferred instead of their full charact…
A Tunable Transition Metal Dichalcogenide Entangled Photon-Pair Source
Maximilian A. Weissflog, Anna Fedotova, Yilin Tang +16
Entangled photon-pair sources are at the core of quantum applications like quantum key distribution, sensing, and imaging. Operation in space-limited and adverse environments such…
Experimental analysis on image resolution of quantum imaging with undetected light through position correlations
Marta Gilaberte Basset, René Sondenheimer, Jorge Fuenzalida +7
Image resolution of quantum imaging with undetected photons is governed by the spatial correlations existing between the photons of a photon pair that has been generated in a nonli…

Aleksa Krstić, Frank Setzpfandt, Sina Saravi
We develop a non-perturbative formulation based on the Green-function quantization method, that can describe spontaneous parametric down-conversion in the high-gain regime in nonli…
Pinhole quantum ghost imaging
Andres Vega, Sina Saravi, Thomas Pertsch +1
We propose a quantum ghost imaging scheme based on biphotons, that, by using a collimated pump beam of the right size for biphoton generation, obviates the need for lenses to achie…
Subdiffraction Quantum Imaging with Undetected Photons
Elkin A. Santos, Thomas Pertsch, Frank Setzpfandt +1
We propose a nonlinear imaging scheme with undetected photons that overcomes the diffraction limit by transferring near-field information at one wavelength to far-field information…
Fundamental resolution limit of quantum imaging with undetected photons
Andres Vega, Elkin A. Santos, Jorge Fuenzalida +5
Quantum imaging with undetected photons relies on the principle of induced coherence without induced emission and uses two sources of photon-pairs with a signal- and an idler photo…
