Quantum key distribution with delayed privacy amplification and its application to security proof of a two-way deterministic protocol
Chi-Hang Fred Fung, Xiongfeng Ma, H. F. Chau +1
Privacy amplification (PA) is an essential post-processing step in quantum key distribution (QKD) for removing any information an eavesdropper may have on the final secret key. In…
Unconditional security proof of a deterministic quantum key distribution with a two-way quantum channel
Hua Lu, Chi-Hang Fred Fung, Xiongfeng Ma +1
In a deterministic quantum key distribution (DQKD) protocol with a two-way quantum channel, Bob sends a qubit to Alice who then encodes a key bit onto the qubit and sends it back t…
An interpretation for the entropy of a black hole
Baocheng Zhang, Qing-yu Cai, Ming-sheng Zhan +1
We investigate the meaning of the entropy carried away by Hawking radiations from a black hole. We propose that the entropy for a black hole measures the uncertainty of the informa…
