The Infinite-Dimensional Quantum Entropy: the Unified Entropy Case

Roman Gielerak, Joanna Wiśniewska, Marek Sawerwain

By a use of the Fredholm determinant theory, the unified quantum entropy notion has been extended to a case of infinite-dimensional systems. Some of the known (in the finite-dimens…

Variational Quantum Eigensolver for Classification in Credit Sales Risk

Joanna Wiśniewska, Marek Sawerwain

The data classification task is broadly utilized in numerous fields of science and it may be realized by different known approaches (e.g. neural networks). However, in this work, q…

A Gramian Approach to Entanglement in Bipartite Finite Dimensional Systems: The case of pure states

Roman Gielerak, Marek Sawerwain

It has been observed that the reduced density matrices of bipartite qudit pure states possess a Gram matrix structure. This observation has opened a possibility of analysing the en…

QTM: computational package using MPI protocol for quantum trajectories method

Marek Sawerwain, Joanna Wiśniewska

The Quantum Trajectories Method (QTM) is one of {the} frequently used methods for studying open quantum systems. { The main idea of this method is {the} evolution of wave functions…
