Long-range Quantum Cryptography: Amplified Quantum Key Distribution (AQKD)
Richard J. Hughes, Jane E. Nordholt
Recently, Takeoka, Guha and Wilde have established a new (loose) upper bound on the secret key capacity of a pure-loss bosonic channel that is several times larger than an error-fr…
Network-Centric Quantum Communications with Application to Critical Infrastructure Protection
Richard J. Hughes, Jane E. Nordholt, Kevin P. McCabe +3
Network-centric quantum communications (NQC) - a new, scalable instantiation of quantum cryptography providing key management with forward security for lightweight encryption, auth…
Security of Decoy-State Protocols for General Photon-Number-Splitting Attacks
Rolando D. Somma, Richard J. Hughes
Decoy-state protocols provide a way to defeat photon-number splitting attacks in quantum cryptography implemented with weak coherent pulses. We point out that previous security ana…
Practical long-distance quantum key distribution system using decoy levels
D. Rosenberg, C. G. Peterson, J. W. Harrington +9
Quantum key distribution (QKD) has the potential for widespread real-world applications. To date no secure long-distance experiment has demonstrated the truly practical operation n…
Long-distance quantum key distribution in optical fiber
P. A. Hiskett, D. Rosenberg, C. G. Peterson +5
Use of low-noise detectors can both increase the secret bit rate of long-distance quantum key distribution (QKD) and dramatically extend the length of a fibre optic link over which…
Long distance decoy state quantum key distribution in optical fiber
Danna Rosenberg, Jim W. Harrington, Patrick R. Rice +6
The theoretical existence of photon-number-splitting attacks creates a security loophole for most quantum key distribution (QKD) demonstrations that use a highly attenuated laser s…
