Retraction: Efficient Concentration Protocols for the Single-Photon Entanglement State with Polarization Feature

The Journal and Authors retract the 10 March 2017 article cited above for the following reasons provided by the authors:

Following publication, the authors realized a fundamental conceptual error in the article's equations. This error extends from Equations (3)–(5) and negates the derivations of the equations and descriptions in the article. The Journal and Chief Editors concur that the reasons for retraction are valid and warranted.
