Applicability of QKD: TerraQuantum view on the NSA's scepticism
D. Sych, A. Kodukhov, V. Pastushenko +3
Quantum communication offers unique features that have no classical analog, in particular, it enables provably secure quantum key distribution (QKD). Despite the benefits of quantu…
Joint eavesdropping on the BB84 decoy state protocol with an arbitrary passive light-source side channel
Danila V. Babukhin, Denis V. Sych
Passive light-source side channel in quantum key distribution (QKD) makes the quantum signals more distinguishable thus provides additional information about the quantum signal to…
Phase randomness in a semiconductor laser: Issue of quantum random-number generation
Roman Shakhovoy, Marius Puplauskis, Violetta Sharoglazova +10
Gain-switched lasers are in demand in numerous quantum applications, particularly, in systems of quantum key distribution and in various optical quantum random number generators. T…
Explicit attacks on BB84 with distinguishable photons
D. Babukhin, D. Kronberg, D. Sych
Distinguishability of photons in non-operational degrees of freedom compromises unconditional security of quantum key distribution since an eavesdropper can improve attack strategi…
Sub-shot-noise-limited fiber-optic quantum receiver
M. L. Shcherbatenko, M. S. Elezov, D. V. Sych +1
We experimentally demonstrate a quantum receiver based on Kennedy scheme for discrimination between two phase-modulated weak coherent states. The receiver is assembled entirely fro…
Efficient generation of temporally shaped photons using nonlocal spectral filtering
Valentin Averchenko, Denis Sych, Christoph Marquardt +1
We study the generation of single-photon pulses with the tailored temporal shape via nonlocal spectral filtering. A shaped photon is heralded from a time-energy entangled photon pa…
