    "abstract": "We show how to communicate Heisenberg-limited continuous (quantum) variables\nbetween Alice and Bob in the case where they occupy two inertial reference\nframes that differ by an unknown Lorentz boost. There are two effects that need\nto be overcome: the Doppler shift and the absence of synchronized clocks.\nFurthermore, we show how Alice and Bob can share Doppler-invariant\nentanglement, and we demonstrate that the protocol is robust under photon loss.",
