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…

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…
