Improving quantum entanglement through single-qubit operations

TL;DR

This paper demonstrates that the entanglement of bipartite quantum states can be probabilistically enhanced using only single-qubit operations, supported by a proposed experiment and numerical simulations.

Contribution

It introduces a method to improve bipartite entanglement through single-qubit operations, which was not previously established.

Findings

Entanglement can be maximized probabilistically with single-qubit operations.

A feasible experimental setup is proposed for implementation.

Numerical simulations confirm the effectiveness of the method.

Abstract

We show that the entanglement of a $2\times 2$ bipartite state can be improved and maximized probabilistically through single-qubit operations only. An experiment is proposed and it is numerically simulated.
