Quantum-mechanical description of optical beams
Iwo Bialynicki-Birula, Zofia Bialynicka-Birula
Quantum mechanics of photons is derived from the theory of representations of the Poincaré group developed by Wigner. This theory places helicity as the most fundamental property;…
Evolution of entanglement under an Ising-like Hamiltonian with particle losses
Konrad Szymański, Krzysztof Pawłowski
We present analytical compact solution for the density matrix and correlation functions of two collective-macroscopic spins evolving via Ising-like Hamiltonian in the presence of p…
Mutual Unbiasedness in Coarse-grained Continuous Variables
Daniel S. Tasca, Piero Sánchez, Stephen P. Walborn +1
The notion of mutual unbiasedness for coarse-grained measurements of quantum continuous variable systems is considered. It is shown that while the procedure of "standard" coarse gr…
Asymptotic properties of entanglement polytopes for large number of qubits
Tomasz Maciążek, Adam Sawicki
Entanglement polytopes have been recently proposed as the way of witnessing the SLOCC multipartite entanglement classes using single particle information. We present first asymptot…
One-parameter Fisher-Rényi complexity: Notion and hydrogenic applications
Irene V. Toranzo, Pablo Sánchez-Moreno, Łukasz Rudnicki +1
In this work the one-parameter Fisher-Rényi measure of complexity for general -dimensional probability distributions is introduced and its main analytic properties are discussed…
