Privacy Amplification in Quantum Key Distribution: Pointwise Bound versus Average Bound
G. Gilbert, M. Hamrick, F. J. Thayer
In order to be practically useful, quantum cryptography must not only provide a guarantee of secrecy, but it must provide this guarantee with a useful, sufficiently large throughpu…
Constraints on Eavesdropping on the BB84 Protocol
G. Gilbert, M. Hamrick
An undetected eavesdropping attack must produce count rate statistics that are indistinguishable from those that would arise in the absence of such an attack. In principle this con…
The Secrecy Capacity of Practical Quantum Cryptography
G. Gilbert, M. Hamrick
Quantum cryptography has attracted much recent attention due to its potential for providing secret communications that cannot be decrypted by any amount of computational effort. Th…
Secrecy, Computational Loads and Rates in Practical Quantum Cryptography
G. Gilbert, M. Hamrick
A number of questions associated with practical implementations of quantum cryptography systems having to do with unconditional secrecy, computational loads and effective secrecy r…
