Title Квантовая информация Type Journal Article
Year 1999 Publication Успехи физических наук Abbreviated Journal УФН
Volume 169 Issue 5 Pages 507-527
Keywords quantum cryptography; QKD, BB84
Abstract Новое направление физики – квантовая информация – возникло на стыке квантовой механики, оптики, теории относительности и программирования, дискретной математики, лазерной физики и спектроскопии и включает в себя вопросы квантовых вычислений, квантовых компьютеров, квантовой телепортации и квантовой криптографии, проблемы декогеренции и спектроскопии одиночных молекул и примесных центров. Сообщается о некоторых новых результатах в этой быстро развивающейся области исследований.

Title After-gate attack on a quantum cryptosystem Type Journal Article
Year 2011 Publication New J. Phys. Abbreviated Journal
Volume 13 Issue 1 Pages 14
Keywords quantum cryptography; hacking; interception; attack; SPD; APD; QKD
Abstract We present a method to control the detection events in quantum key distribution systems that use gated single-photon detectors. We employ bright pulses as faked states, timed to arrive at the avalanche photodiodes outside the activation time. The attack can remain unnoticed, since the faked states do not increase the error rate per se. This allows for an intercept-resend attack, where an eavesdropper transfers her detection events to the legitimate receiver without causing any errors. As a side effect, afterpulses, originating from accumulated charge carriers in the detectors, increase the error rate. We have experimentally tested detectors of the system id3110 (Clavis2) from ID Quantique. We identify the parameter regime in which the attack is feasible despite the side effect. Furthermore, we outline how simple modifications in the implementation can make the device immune to this attack.

Title Single-photon superconducting detectors for practical high-speed quantum cryptography Type Miscellaneous
Year 2001 Publication OFCC/ICQI Abbreviated Journal OFCC/ICQI
Volume Issue Pages Pa3
Keywords NbN SSPD, SNSPD, QKD, quantum cryptography
Abstract We have developed an ultrafast superconducting single-photon detector with negligible dark counting rate. The detector is based on an ultrathin, submicron-wide NbN meander-type stripe and can detect individual photons in the visible to near-infrared wavelength range at a rate of at least 10 Gb/s. The above counting rate allows us to implement the NbN device to unconditionally secret quantum key distRochester, New Yorkribution in a practical, high-speed system using real-time Vernam enciphering.

Title Real-time GHz-rate counting of infrared photons using nanostructured NbN superconducting detectors Type Conference Article
Year 2003 Publication CLEO/QELS Abbreviated Journal CLEO/QELS
Volume Issue Pages CThM8
Keywords NbN SSPD; SNSPD; Infrared; Quantum detectors; Detectors; Photon counting; Quantum communications; Quantum cryptography; Single photon detectors; Superconductors
Abstract We demonstrate that our ultrathin, nanometer-width NbN superconducting single-photon detectors are capable of above 1-GHz-frequency, real-time counting of near-infrared photons. The measured system jitter of the detector is below 15 ps.
