Construction of quantum states by special superpositions of coherent states
P. Adam, E. Molnar, G. Mogyorosi +3
We consider the optimal approximation of certain quantum states of a harmonic oscillator with the superposition of a finite number of coherent states in phase space placed either o…
Optimization of periodic single-photon sources
Peter Adam, Matyas Mechler, Imre Santa +1
We introduce a theoretical framework which is suitable for the description of all spatial and time-multiplexed periodic single-photon sources realized or proposed thus far. Our mod…
Magnetoplasmons of the tilted-anisotropic Dirac cone material (BEDT-TTF)I
Judit Sári, Csaba Toke, Mark O. Goerbig
We study the collective modes of a low-energy continuum model of the quasi-two-dimensional electron liquid in a layer of the organic compound (BEDT-TTF)I in a perpendic…
Cyclicity degrees of finite groups
Marius Tărnăuceanu, László Tóth
We introduce and study the concept of cyclicity degree of a finite group . This quantity measures the probability of a random subgroup of to be cyclic. Explicit formulas are…
Counting solutions of quadratic congruences in several variables revisited
László Tóth
Let denote the number of incongruent solutions of the quadratic congruence (mod ), where $\boldsymbol{a}=(a_1,\ldots…
Entropy rate of message sources driven by quantum walks
Bálint Kollár, Mátyás Koniorczyk
The amount of information generated by a discrete time stochastic processes in a single step can be quantified by the entropy rate. We investigate the differences between two discr…
