Quantum cryptography
Dag Roar Hjelme, Lars Lydersen, Vadim Makarov
This is a chapter on quantum cryptography for the book "A Multidisciplinary Introduction to Information Security" to be published by CRC Press in 2011/2012. The chapter aims to int…
Comment on "Resilience of gated avalanche photodiodes against bright illumination attacks in quantum cryptography"
Lars Lydersen, Vadim Makarov, Johannes Skaar
This is a comment on the publication by Yuan et al. [Appl. Phys. Lett. 98, 231104 (2011); arXiv:1106.2675v1 [quant-ph]].
Superlinear threshold detectors in quantum cryptography
Lars Lydersen, Nitin Jain, Christoffer Wittmann +5
We introduce the concept of a superlinear threshold detector, a detector that has a higher probability to detect multiple photons if it receives them simultaneously rather than at…
Device calibration impacts security of quantum key distribution
Nitin Jain, Christoffer Wittmann, Lars Lydersen +5
Characterizing the physical channel and calibrating the cryptosystem hardware are prerequisites for establishing a quantum channel for quantum key distribution (QKD). Moreover, an…
Secure gated detection scheme for quantum cryptography
Lars Lydersen, Vadim Makarov, Johannes Skaar
Several attacks have been proposed on quantum key distribution systems with gated single-photon detectors. The attacks involve triggering the detectors outside the center of the de…
