Self-stabilized high-dimensional quantum key distribution on a metropolitan free-space link
Karolina Dziwulska, Christopher Spiess, Sarika Mishra +3
Quantum communication technologies capable of operating reliably across heterogeneous optical channels are essential for scalable metropolitan quantum networks. Here we demonstrate…
Noise resilient real-time phase imaging via undetected light
Josué R. León-Torres, Patrick Hendra, Yugant Mukeshbhai Hadiyal +5
Quantum imaging with undetected light has recently emerged as a technique in which quantum correlations and nonlinear interferometry are combined to decouple illumination and detec…
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…
Ad-hoc hybrid-heterogeneous metropolitan-range quantum key distribution network
Matthias Goy, Jan Krause, Ãmer Bayraktar +37
This paper presents the development and implementation of a versatile ad-hoc metropolitan-range Quantum Key Distribution (QKD) network. The approach presented integrates various ty…
