    "abstract": "We develop the theory of continuous-variable quantum secret sharing and\npropose its interferometric realization using passive and active optical\nelements. In the ideal case of infinite squeezing, a fidelity ${\\cal F}$ of\nunity can be achieved with respect to reconstructing the quantum secret. We\nquantify the reduction in fidelity for the (2,3) threshold scheme due to finite\nsqueezing and establish the condition for verifying that genuine quantum secret\nsharing has occurred.",
