Quantum cryptography beyond key distribution: theory and experiment
Mathieu Bozzio, Claude Crépeau, Petros Wallden +1
Owing to its fundamental principles, quantum theory holds the promise to enhance the security of modern cryptography, from message encryption to anonymous communication, digital si…
Quantum Communication with Quantum Dots Beyond Telecom Wavelengths via Hollow-Core Fibers
Lorenzo Carosini, Francesco Giorgino, Patrik I. Sund +7
Quantum dot single-photon sources are promising for quantum communication. Yet, the most advanced devices operate near 900 nm, where standard single-mode fibers experience signific…
Performance of Practical Quantum Oblivious Key Distribution
Mariano Lemus, Peter Schiansky, Manuel Goulão +5
Motivated by the applications of secure multiparty computation as a privacy-protecting data analysis tool, and identifying oblivious transfer as one of its main practical enablers,…
Purifying photon indistinguishability through quantum interference
Carlos F. D. Faurby, Lorenzo Carosini, Huan Cao +9
Indistinguishability between photons is a key requirement for scalable photonic quantum technologies. We experimentally demonstrate that partly distinguishable single photons can b…
Asymmetric two-photon response of an incoherently driven quantum emitter
Lennart Jehle, Lena M. Hansen, Patrik I. Sund +7
Quantum emitters promise to emit exactly one photon with high probability when pumped by a laser pulse. However, even in ideal systems, re-excitation during a laser pulse causes th…
Multi-photon emission from a resonantly pumped quantum dot
Francesco Giorgino, Patrik Zahálka, Lennart Jehle +4
Resonance fluorescence of natural or artificial atoms constitutes a prime method for generating non-classical light. While most efforts have focused on producing single-photons, mu…
