  We study the detection of continuous-variable entanglement, for which most of
the existing methods designed so far require a full specification of the
devices, and we present protocols for entanglement detection in a scenario
where the measurement devices are completely uncharacterised. We first
generalise, to the continuous variable regime, the seminal results by Buscemi
[PRL 108, 200401(2012)] and Branciard et al. [PRL 110, 060405 (2013)], showing
that all entangled states can bedetected in this scenario. Most importantly, we
then describe a practical protocol that allows for the
measurement-device-independent certification of entanglement of all two-mode
entangled Gaussian states. This protocol is feasible with current technology as
it makes only use of standard optical setups such as coherent states and
homodyne measurements.
