From Quantum Chaos to Classical Chaos via Gain-Induced Measurement Dynamics in a Photon Gas

Violetta Sharoglazova, Marius Puplauskis, Lotte Hof +1

How classical chaos emerges from quantum mechanics remains a central open question, as the unitary evolution of isolated quantum systems forbids exponential sensitivity to initial…

Reaffirming a Challenge to Bohmian Mechanics

Jan Klaers, Violetta Sharoglazova, Marius Puplauskis

In our recent work, we reported the first measurement of the speed of tunnelling particles using a coupled waveguide system. The measured speed is operationally defined through a c…

Inverse solving the Schrödinger equation for precision alignment of a microcavity

Charlie Mattschas, Marius Puplauskis, Chris Toebes +2

In paraxial approximation, the electromagnetic eigenmodes inside an optical microresonator can be derived from a Schrödinger-type eigenvalue problem. In this framework, tilting the…

Particle motion associated with wave function density gradients

Jan Klaers, Violetta Sharoglazova, Chris Toebes

We study the quantum mechanical motion of massive particles in a system of two coupled waveguide potentials, where the population transfer between the waveguides effectively acts a…

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…

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…

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…
