In order to model the spectroscopic and scattering properties of a quantum system, we propose explore new absorbing complex-type optical potential based on combination cosine functions. This function provides high degree smoothness joint with physical real-type potential. The capabilities this are investigated in terms its effect otherwise freely evolving dynamics. We use our open-source progra...

For many–particle systems, quantum information in base n can be defined by partitioning the set of states according to the outcomes of n–ary (joint) observables. Thereby, k particles can carry k nits. With regards to the randomness of single outcomes, a context translation principle is proposed. Quantum randomness is related to the uncontrollable degrees of freedom of the measurement interface,...

This paper gives new foundations of quantum state reduction without appealing to the projection postulate for the probe measurement. For this purpose, the quantum Bayes principle is formulated as the most fundamental principle for determining the state of a quantum system, and the joint probability distribution for the outcomes of local successive measurements on a noninteracting entangled syst...
