Quantum Authenticated Key Expansion with Key Recycling
Wen Yu Kon, Jefferson Chu, Kevin Han Yong Loh +5
Data privacy and authentication are two main security requirements for remote access and cloud services. While QKD has been explored to address data privacy concerns, oftentimes it…
Experimental symmetric private information retrieval with measurement-device-independent quantum network
Chao Wang, Wen Yu Kon, Hong Jie Ng +1
Secure information retrieval is an essential task in today's highly digitised society. In some applications, it may be necessary that user query's privacy and database content's se…
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…
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…
