Contribution

It introduces a novel scheme for activating entanglement using non-classical correlations in optomechanical systems, connecting theory with current experimental capabilities.

Findings

Activation of entanglement demonstrated under specific conditions

Relates activation scheme to current experimental state of the art

Provides an alternative method to reveal mechanical nonclassicality

Abstract

We propose an optomechanical setup where the activation of entanglement through the pre-availability of non-classical correlations can be demonstrated experimentally. We analyse the conditions under which the scheme is successful and relate them to the current experimental state of the art. The successful activation of entanglement embodies an interesting alternative to current settings for the revelation of fully mechanical nonclassicality.
