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…
