# Entangling and disentangling capacities of nonlocal maps

## TL;DR

This paper explores the entangling and disentangling abilities of non-unitary quantum operations, specifically unital CPTP maps on two qubits, expanding understanding beyond unitary operations.

## Contribution

It introduces the analysis of entangling and disentangling capacities of non-unitary, unital CPTP maps, a less-studied area in quantum information.

## Key findings

- Characterization of capacities of unital CPTP maps
- Comparison with unitary operation capacities
- Insights into nonlocal quantum operation capabilities

## Abstract

Entangling and disentangling capacities are the key manifestation of the nonlocal content of a quantum operation. A lot of effort has been put recently into investigating (dis)entangling capacities of unitary operations, but very little is known about capacities of non-unitary operations. Here we investigate (dis)entangling capacities of unital CPTP maps acting on two qubits.
