Reconstructing 2D spatial modes for classical and quantum light
Valentin A. Averchenko, Gaetano Frascella, Mahmoud Kalash +2
We propose a method for finding 2D spatial modes of thermal field through a direct measurement of the field intensity and an offline analysis of its spatial fluctuations. Using thi…
Towards third-order parametric down-conversion in optical fibers
Andrea Cavanna, Jonas Hammer, Cameron Okoth +8
Optical fibers have been considered an optimal platform for third-order parametric down-conversion since they can potentially overcome the weak third-order nonlinearity by their lo…
Idealised EPR states from non-phase matched parametric down conversion
C. Okoth, E. Kovlakov, F. Boensel +4
Entanglement of high dimensional states is becoming increasingly important for quantum communication and computing. The most common source of entangled photons is spontaneous param…
Separated Schmidt modes in the angular spectrum of biphotons
N. A. Borshchevskaia, F. Just, K. G. Katamadze +2
We prepare qudits based on angular multimode biphoton states by modulating the pump angular spectrum. The modes are prepared in the Schmidt basis and their intensity distributions…
Microscale generation of entangled photons without momentum conservation
C. Okoth, A Cavanna, T. Santiago-Cruz +1
We report, for the first time, the generation of entangled photon pairs via type-0 spontaneous parametric down conversion in an ultra-thin wafer of lithium niobate in which momentu…
Seeded and unseeded high order parametric down conversion
Cameron Okoth, Andrea Cavanna, Nicolas Joly +1
Spontaneous parametric down conversion (SPDC) has been one of the foremost tools in quantum optics for over five decades. Over that time it has been used to demonstrate some of the…
Multiphoton nonclassical light from clusters of single-photon emitters
Luo Qi, Mathieu Manceau, Andrea Cavanna +8
We study nonclassical features of multiphoton light emitted by clusters of single-photon emitters. As signatures of nonclassicality, we use violation of inequalities for normalized…
Tunable optical parametric generator based on the pump spatial walk-off
Andrea Cavanna, Felix Just, Polina R. Sharapova +3
We suggest a novel optical parametric generator (OPG) in which one of the down-converted beams is spontaneously generated along the Poynting vector of the pump beam. In this config…
Detection of non-classical space-time correlations with a novel type of single-photon camera
Felix Just, Mykhaylo Filipenko, Andrea Cavanna +9
During the last decades, multi-pixel detectors have been developed capable of registering single photons. The newly developed Hybrid Photon Detector camera has a remarkable propert…
Compensation of anisotropy effects in the generation of two-photon light
Andrea Cavanna, Angela M. Pérez, Felix Just +2
We analyse a method to compensate for anisotropy effects in the spatial distribution of parametric down-conversion (PDC) radiation in bulk crystals. In this method, a single nonlin…
Effects of anisotropy in a nonlinear crystal for squeezed vacuum generation
A. M. Pérez, F. Just, A. Cavanna +2
Squeezed vacuum (SV) can be obtained by an optical parametric amplifier (OPA) with the quantum vacuum state at the input. We are interested in a degenerate type-I OPA based on para…
Transverse Entanglement of Biphotons
Felix Just, Andrea Cavanna, Maria V. Chekhova +1
We measure the transverse entanglement of photon pairs on their propagation from the near to the far field of spontaneous parametric downconversion (SPDC). The Fedorov ratio, depen…
Review on recent groundbreaking experiments on quantum communication with orthogonal states
A. Avella, G. Brida, D. Carpentras +5
In recent years Quantum Key Distribution (QKD) has emerged as the most paradigmatic example of Quantum technology allowing the realization of intrinsically secure communication lin…
Experimental realization of Counterfactual Quantum Cryptography
Giorgio Brida, Andrea Cavanna, Ivo Pietro Degiovanni +2
In counterfactual QKD information is transfered, in a secure way, between Alice and Bob even when no particle carrying the information is in fact transmitted between them. In this…
