Abstract

A study was conducted to demonstrate which separable pure two-qubit states have to be used to create as much entanglement as possible by applying a general two-qubit gate. It was shown which unitary operators are able to create a maximally entangled state. For demonstration purposes, two examples of unitary operations for which it is possible to determine the maximal amount of some particular measure of entanglement were considered.
