We introduce a measure of efficiency for the photon subtraction protocol aimed at entanglement concentration on a single copy of bipartite continuous variable state. We then show that iterating the protocol does not lead to higher efficiency than a single application. In order to overcome this limit we present an adaptive version of the protocol able to enhance its efficiency.

Abstract
We introduce a measure of efficiency for the photon subtraction protocol aimed at entanglement concentration on a single copy of bipartite continuous variable state. We then show that iterating the protocol does not lead to higher efficiency than a single application. In order to overcome this limit we present an adaptive version of the protocol able to enhance its efficiency.File in questo prodotto:
