Brazilian Twin Photons 32nd anniversary
Renné Medeiros de Araújo, Raphael César Souza Pimenta, Lucas Marques Fagundes +4
We present a historical review of the development and impact of spontaneous parametric down-conversion (SPDC) in Brazil, marking over three decades since the first twin-photon expe…
Characterization of Generalized Coherent States through Intensity-Field Correlations
Ignacio Salinas Valdivieso, Victor Gondret, Gerd Hartmann S. +3
Non-Gaussian quantum states of light are essential resources for quantum information processing and precision metrology. Among them, generalized coherent states (GCS), which natura…
Non-Markovian spontaneous emission in a tunable cavity formed by atomic mirrors
Annyun Das, Pablo Solano, Kanu Sinha
We analyze the non-Markovian spontaneous emission dynamics of a two-level test atom placed in a cavity formed by two atomic arrays in a waveguide quantum electrodynamics (QED) setu…
Benchmarking weak randomness in Quantum and Natural Sources
Maciej Stankiewicz, Roberto Salazar, Mikołaj Czechlewski +7
Private randomness is a fundamental resource for cryptography, security proofs, and information processing. Quantum devices offer a unique advantage by amplifying weak randomness s…
The future of secure communications: device independence in quantum key distribution
Seyed Arash Ghoreishi, Giovanni Scala, Renato Renner +4
In the ever-evolving landscape of quantum cryptography, Device-independent Quantum Key Distribution (DI-QKD) stands out for its unique approach to ensuring security based not on th…
Observation of non-Markovian Radiative Phenomena in Structured Photonic Lattices
Rodrigo A. Vicencio, Fabiola G. L. Carcamo-Macaya Diego Román-Cortés, Pablo Solano
The spectral structure of a photonic reservoir shapes radiation phenomena for embedded quantum emitters. We implement an all-optical analog to study such an effect, particularly to…
