Sampled sub-block hashing for large input randomness extraction

Hong Jie Ng, Wen Yu Kon, Ignatius William Primaatmaja +2

Randomness extraction is an essential post-processing step in practical quantum cryptography systems. When statistical fluctuations are taken into consideration, the requirement of…

Provably-secure quantum randomness expansion with uncharacterised homodyne detection

Chao Wang, Ignatius William Primaatmaja, Hong Jie Ng +5

Quantum random number generators (QRNGs) are able to generate numbers that are certifiably random, even to an agent who holds some side-information. Such systems typically require…

Discrete-variable quantum key distribution with homodyne detection

Ignatius William Primaatmaja, Cassey Crystania Liang, Gong Zhang +3

Most quantum key distribution (QKD) protocols can be classified as either a discrete-variable (DV) protocol or continuous-variable (CV) protocol, based on how classical information…

Estimating the photon-number distribution of photonic channels with realistic devices and applications in photonic quantum information processing

Emilien Lavie, Ignatius William Primaatmaja, Wen Yu Kon +2

Characterising the input-output photon-number distribution of an unknown optical quantum channel is an important task for many applications in quantum information processing. Ideal…

Securing practical quantum communication systems with optical power limiters

Gong Zhang, Ignatius William Primaatmaja, Jing Yan Haw +3

Controlling the energy of unauthorized light signals in a quantum cryptosystem is an essential criterion for implementation security. Here, we propose a passive optical power limit…

Practical quantum key distribution with non-phase-randomized coherent states

Li Liu, Yukun Wang, Emilien Lavie +4

Quantum key distribution (QKD) based on coherent states is well known for its implementation simplicity, but it suffers from loss-dependent attacks based on optimal unambiguous sta…
