Fock State Sampling Method -- Characteristic temperature of maximal fluctuations for interacting bosons in box potentials
M. B. Kruk, T. Vibel, J. Arlt +3
We study the statistical properties of a gas of interacting bosons trapped in a box potential in two and three dimensions. Our primary focus is the characteristic temperature $\tch…
Classicality of the Bogoliubov transformations and the dynamical Casimir effect through the reduced state of the field
Tomasz Linowski, Łukasz Rudnicki
We use the reduced state of the field formalism [Entropy 21, 705 (2019)] to derive conditions under which a Bogoliubov transformation can be considered semi-classical. We apply thi…
Arrival time in quantum mechanics (demonstrated in geometrical order)
Jerzy Kijowski
A geometric construction of the arrival time in conventional quantum mechanics is presented. It is based on a careful mathematical analysis of different quantization procedures for…
Entangled States are Harder to Transfer than Product States
Tony J. G. Apollaro, Salvatore Lorenzo, Francesco Plastina +2
The distribution of entangled states is a key task of utmost importance for many quantum information processing protocols. A commonly adopted setup for distributing quantum states…
