    "abstract": "We propose an efficient scheme for sharing a continuous variable quantum\nsecret using passive optical interferometry and squeezers: this efficiency is\nachieved by showing that a maximum of two squeezers is required to replicate\nthe secret state, and we obtain the cheapest configuration in terms of total\nsqueezing cost. Squeezing is a cost for the dealer of the secret as well as for\nthe receivers, and we quantify limitations to the fidelity of the replicated\nsecret state in terms of the squeezing employed by the dealer.",
