Mode-selective nonlinear interference for high-brightness and high-purity fiber-coupled SPDC sources
Carlos Sevilla-Gutiérrez, Purujit Singh Chauhan, Varun Raj Kaipalath +1
Single-mode-fiber-coupled spontaneous parametric down-conversion (SPDC) sources are a key resource for photonic quantum technologies, but in single-crystal geometries brightness, h…
Gaussian mode coupling of spectrally broadband photons from bulk spontaneous parametric down-conversion: A spatial-spectral mode analysis of fiber coupling
Carlos Sevilla-Gutiérrez, Varun Raj Kaipalath, Fabian Steinlechner
Photon sources based on spontaneous parametric down-conversion (SPDC) are central to experimental quantum optics and quantum technologies. Their performance is commonly quantified…
Benchmarking Gaussian and non-Gaussian input states with a hybrid sampling platform
Michael Stefszky, Kai-Hong Luo, Jan-Lucas Eickmann +22
The original boson sampling paradigm-consisting of multiple single-photon input states, a large interferometer, and multi-channel click detection-was originally proposed as a photo…
Frequency subspace encoding for multiplexed quantum secret sharing
Meritxell Cabrejo-Ponce, Christopher Spiess, Carlos Sevilla-Gutiérrez +1
Quantum secret sharing (QSS) is a multi-party quantum communication protocol that can be realized with bipartite entanglement and relative phase encoding. Previous implementations…
