Security proofs for practical QKD: variations, techniques, gaps, and limitations
Devashish Tupkary, Ernest Y. -Z. Tan, Shlok Nahar +2
We review the current status of security proofs for practical decoy-state Quantum Key Distribution using the BB84 protocol, focusing on optical implementations with weak coherent p…
Performance of BB84 without decoy states under varying announcement structures
Zhiyao Wang, Aodhán Corrigan, Norbert Lütkenhaus
In phase-randomized weak coherent pulse (WCP) implementations of Quantum Key Distribution (QKD) BB84 protocol, the decoy method is often used to compensate BB84's vulnerability aga…
A rigorous and complete security proof of decoy-state BB84 quantum key distribution
Devashish Tupkary, Shlok Nahar, Amir Arqand +2
We present a rigorous and complete security proof of the decoy-state BB84 quantum key distribution (QKD) protocol. Our analysis aims to achieve a high standard of mathematical rigo…
Drone- and Vehicle-Based Quantum Key Distribution
Andrew Conrad, Roderick Cochran, Daniel Sanchez-Rosales +18
Quantum key distribution is a point-to-point communication protocol that leverages quantum mechanics to enable secure information exchange. Commonly, the transmitter and receiver s…
Improved finite-size effects in QKD protocols with applications to decoy-state QKD
Lars Kamin, Devashish Tupkary, Norbert Lütkenhaus
We present a finite-size security proof for generic quantum key distribution protocols against independent and identically distributed collective attacks and extend it to coherent…
Postselection technique for optical Quantum Key Distribution with improved de Finetti reductions
Shlok Nahar, Devashish Tupkary, Yuming Zhao +2
The postselection technique is an important proof technique for proving the security of quantum key distribution protocols against coherent attacks. In this work, we go through mul…
