Provable entanglement and information cost for qubit-based quantum key-distribution protocols
G. M. Nikolopoulos, A. Khalique, G. Alber
Provable entanglement has been shown to be a necessary precondition for unconditionally secure key generation in the context of quantum cryptographic protocols. We estimate the max…

Robustness of the BB84 quantum key distribution protocol against general coherent attacks
Georgios M. Nikolopoulos, Gernot Alber
It is demonstrated that for the entanglement-based version of the Bennett-Brassard (BB84) quantum key distribution protocol, Alice and Bob share provable entanglement if and only i…
