Realistic vulnerabilities of decoy-state quantum key distribution
I. S. Sushchev, K. E. Bugai, S. N. Molotkov +6
We analyze realistic vulnerabilities of decoy-state quantum key distribution (QKD) arising from the combination of laser damage attack (LDA) and unambiguous state discrimination (U…
Practical Quantum Key Distribution with Geometrically Uniform States
Konstantin S. Kravtsov, Sergei N. Molotkov
In this paper we propose a practical quantum key distribution protocol based on geometrically uniform states and a standard decoy state technique. The protocol extends the ideas us…
Relativistic quantum key distribution system with one-way quantum communication
K. S. Kravtsov, I. V. Radchenko, S. P. Kulik +1
Unambiguous state discrimination (USD) is one of the major obstacles for practical quantum key distribution (QKD). Often overlooked, it allows efficient eavesdropping in majority o…
Minimalist design of a robust real-time quantum random number generator
K. S. Kravtsov, I. V. Radchenko, S. P. Kulik +1
We present a simple and robust construction of a real-time quantum random number generator (QRNG). Our minimalist approach ensures stable operation of the device as well as its sim…
Relativistic Quantum Cryptography
I. V. Radchenko, K. S. Kravtsov, S. P. Kulik +1
Quantum key distribution (QKD) is a concept of secret key exchange supported by fundamentals of quantum physics. Its perfect realization offers unconditional key security, however,…
Role of causality in ensuring unconditional security of relativistic quantum cryptography
S. N. Molotkov, S. S. Nazin
The problem of unconditional security of quantum cryptography (i.e. the security which is guaranteed by the fundamental laws of nature rather than by technical limitations) is one…
