Lorentz-covariant reduced spin density matrix and EPR-Bohm correlations
P. Caban, J. Rembielinski
We show that it is possible to define a Lorentz-covariant reduced spin density matrix for massive particles. Such a matrix allows one to calculate the mean values of observables co…

Unstable particles as open quantum systems
P. Caban, J. Rembielinski, K. A. Smolinski +1
We present the probability preserving description of the decaying particle within the framework of quantum mechanics of open systems taking into account the superselection rule pro…

Kraus representation of destruction of states for one qudit
P. Caban, K. A. Smolinski, Z. Walczak
Quantum operations arise naturally in many fields of quantum information theory and quantum computing. One of the simplest example of quantum operation is the von Neumann-Lueders m…
