Passive superresolution imaging of incoherent objects

Jernej Frank, Alexander Duplinskiy, Kaden Bearne +1

We investigate Hermite Gaussian Imaging (HGI) -- a novel passive super-resolution technique -- for complex 2D incoherent objects in the sub-Rayleigh regime. The method consists of…

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…

Wavelength- and time-division multiplexing via pump current variation of a pulsed semiconductor laser -- a method of synchronization for quantum key distribution

Roman Shakhovoy, Marius Puplauskis, Violetta Sharoglazova +4

The dependence of the semiconductor laser wavelength on the pump current is a well-known phenomenon, which is generally attributed to a change in the refractive index of the active…

Direct phase modulation via optical injection: theoretical study

Roman Shakhovoy, Marius Puplauskis, Violetta Sharoglazova +4

Direct phase modulation via optical injection is a newly developed method for coding the phase of a gain-switched laser, which meets high requirements placed on transmitters for qu…

Influence of chirp, jitter and relaxation oscillations on probabilistic properties of laser pulse interference

Roman Shakhovoy, Violetta Sharoglazova, Alexander Udaltsov +3

Interference of laser pulses is an essential ingredient of quantum randomness; therefore, probabilistic properties of laser pulses gains new relevance. Here, we consider in detail…

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…
