An optical-fibre-integrated buffer for packet-switched quantum networks
Daniel Spegel-Lexne, Joakim Argillander, Martin Clason +5
Packet-switched quantum networks require buffers that can delay qubit payloads while routing information is read out in real time. Previous approaches have not provided this functi…
Deployed trusted-node quantum key distribution over 300 km with a multi-core fiber access link
Martin Clason, Joakim Argillander, Didrik Bergström +8
Quantum key distribution (QKD) is increasingly considered for deployment in realistic communication networks, where long distances, heterogeneous fiber infrastructure, and coexiste…
High-dimensional detection-loophole-free measurement-device-independent quantum random number generator
Joakim Argillander, Daniel Spegel-Lexne, Martin Clason +4
Certifying random number generators is challenging, especially in security-critical fields like cryptography. Here, we demonstrate a measurement-device-independent quantum random n…
Certifying semi-device-independent security via wave-particle duality experiments
Chithra Raj, Tushita Prasad, Anubhav Chaturvedi +8
Wave-particle duality is known to be equivalent to an entropic uncertainty relation based on the min- and max-entropies, which have a clear operational meaning in quantum cryptogra…
Storage Buffer of Polarization Quantum States Based on a Poled-Fiber Phase Modulator
Daniel Spegel-Lexne, João Manoel Barbosa Pereira, Alvaro Alarcón +6
Dynamic storage of qubits is crucial for quantum communication networks. Here we present an adjustable buffer capable of storing photonic polarization quantum states in a fiber loo…
Experimental demonstration of the equivalence of entropic uncertainty with wave-particle duality
Daniel Spegel-Lexne, Santiago Gómez, Joakim Argillander +4
Wave-particle duality is one of the most striking and counter-intuitive features of quantum mechanics, illustrating that two incompatible observables cannot be measured simultaneou…
All-in-fiber dynamic orbital angular momentum mode sorting
Alvaro Alarcón, Santiago Gómez, Daniel Spegel-Lexne +5
The orbital angular momentum (OAM) spatial degree of freedom of light has been widely explored in many applications, including telecommunications, quantum information and light-bas…
Dynamic generation of photonic spatial quantum states with an all-fiber platform
A. Alarcón, J. Argillander, D. Spegel-Lexne +1
Photonic spatial quantum states are a subject of great interest for applications in quantum communication. One important challenge has been how to dynamically generate these states…
