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.…

Characterizing and exploiting cross-talk effect in SPAD arrays for two-photon interference
Sergei Kulkov, Lada Radmacherova, Ondrej Matousek +7
SPAD arrays are becoming a popular choice for measuring two-photon interference effects thanks to their high timing precision, fast readout, and high quantum efficiency. However, s…

Inter-pixel cross-talk as background to two-photon interference effects in SPAD arrays
Sergei Kulkov, Tereza Potuckova, Ermanno Bernasconi +6
Cross-talk is a well-known feature of single-photon avalanche detectors. It is especially important to account for this effect in applications involving coincidences of two or more…
