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…
Security analysis of quantum key distribution with small block length and its application to quantum space communications
Charles Ci-Wen Lim, Feihu Xu, Jian-Wei Pan +1
The security of real-world quantum key distribution (QKD) critically depends on the number of data points the system can collect in a fixed time interval. To date, state-of-the-art…
Loss-tolerant quantum key distribution with a twist
J. Eli Bourassa, Ignatius William Primaatmaja, Charles Ci Wen Lim +1
The security of measurement device-independent quantum key distribution (MDI QKD) relies on a thorough characterization of one's optical source output, especially any noise in the…
Provably-secure symmetric private information retrieval with quantum cryptography
Wen Yu Kon, Charles Ci Wen Lim
Private information retrieval (PIR) is a database query protocol that provides user privacy, in that the user can learn a particular entry of the database of his interest but his q…
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…
