Full-field mapping of spatially varying polarization entanglement generated from spontaneous parametric down-conversion
Cheng Li, Girish Kulkarni, Isaac Soward +6
Two-photon states generated from spontaneous parametric down-conversion (SPDC) can display entanglement in all degrees of freedom (DoFs) of light, including spatial, temporal, and…
Studies of ultrafast dynamics in substrate-free nanoparticles at ELI using Timepix3 optical camera
Dmitrij Å evaev, Andrei Nomerotski, Peter Å vihra +7
We present a novel application of the Timepix3 optical camera (Tpx3Cam) for investigating ultrafast dynamics in substrate-free nanoparticles at the Extreme Light Infrastructure Eur…
Tunable Quantum Interference in Free Space with a Liquid-Crystal Metagrating
Maria Gorizia Ammendola, Italo Machuca Flores, Sneha Dey +9
Structured optical materials provide a promising platform for photonic quantum information processing in free space. Beam splitters, a fundamental building block of photonic circui…
Intensified optical camera with Timepix4 readout
Erik Hogenbirk, Andrei Nomerotski, Bram Bouwens +7
We report the first characterization results of an optical time-stamping camera based on the Timepix4 chip coupled to a fully depleted optical silicon sensor and fast image intensi…
Stellar physics at sub-nanoradian angular resolution
P. Batista, J. Biteau, C. Carlile +36
Many stars -- if they could be imaged with enough angular resolution -- would exhibit features expected from theory but not possible to extract from spectra. We may group these by…
Accidental coincidences in camera-based high-dimensional entanglement certification
Raphaël Guitter, Baptiste Courme, Chloé Vernière +3
High-dimensional entangled states, such as spatially-entangled photon pairs produced by Spontaneous Parametric Down-Conversion (SPDC), are a key resource for quantum technologies.…
