We study the detection of continuous-variable entanglement, for which most existing methods designed so far require a full specification devices, and we present protocols entanglement in scenario where measurement devices are completely uncharacterized. first generalize, to continuous variable regime, seminal results by Buscemi [Phys. Rev. Lett. 108, 200401 (2012)] Branciard et al. 110, 060405 ...
