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…
Quantum noise extraction from the interference of laser pulses in optical quantum random number generator
Roman Shakhovoy, Denis Sych, Violetta Sharoglazova +3
We propose a method for quantum noise extraction from the interference of laser pulses with random phase. Our technique is based on the calculation of a parameter, which we called…
Bounding light source side channels in QKD via Hong-Ou-Mandel interference
Alexander Duplinskiy, Denis Sych
Side-channel attacks on practical quantum key distribution systems compromise its security. Although some of these attacks can be taken into account, the general recipe of how to e…
