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…
