We propose a modification of the protocol which can be translated into a real experiment using present-day technology. In the proposed experiment, the quantum reduction of the multiparty communication complexity would require an efficiency η > 0.05, achievable with detectors of σ > 0.47, for four parties, and η > 0.17 (σ > 0.55) for three parties.application/pdf4 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Guess my numberQuantum protocolinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1103/PhysRevA.71.020301
