# Entanglement production by evolution operator

## TL;DR

This paper investigates how evolution operators generate entanglement in quantum systems, specifically analyzing a two-qubit register's entanglement production using a previously introduced measure, with potential implementations in atomic systems.

## Contribution

It applies a measure of entanglement production to a two-qubit system, providing explicit calculations and potential physical realizations.

## Key findings

- Calculated the measure of evolutional entanglement production for a two-qubit system
- Demonstrated possible implementations in atomic double well or trapped atom systems
- Provided insights into entanglement dynamics under evolution operators

## Abstract

Entanglement production, generated by an evolution operator, is considered. The measure of entanglement production, introduced earlier by one of the authors, is employed. As an illustration, a two-qubit register is studied and the corresponding measure of evolutional entanglement production is calculated. Such two-qubit registers can be realized by atomic systems in a double well or by trapped atoms with two coherent modes.
