Quantum Chernoff divergence in advantage distillation for quantum key distribution and device-independent quantum key distribution
Mikka Stasiuk, Norbert Lütkenhaus, Ernest Y. -Z. Tan
Device-independent quantum key distribution (DIQKD) aims to mitigate adversarial exploitation of imperfections in quantum devices, by providing an approach for secret key distillat…

Device-independent uncloneable encryption
Srijita Kundu, Ernest Y. -Z. Tan
Uncloneable encryption, first introduced by Broadbent and Lord (TQC 2020) is a quantum encryption scheme in which a quantum ciphertext cannot be distributed between two non-communi…

Entropy bounds for device-independent quantum key distribution with local Bell test
Ernest Y. -Z. Tan, Ramona Wolf
One of the main challenges in device-independent quantum key distribution (DIQKD) is achieving the required Bell violation over long distances, as the channel losses result in low…
