Abstract
We discuss sharing quantum secrets via optical interferometry and squeezing. A secret quantum state for a single-mode field is encoded into a multimode field as an entangled state and distributed to a set of players so that certain subsets can decode the secret states, and others cannot learn anything about the state. In particular, we discuss the (k,n)-threshold scheme for optics and specifically the (2,3) scheme. An arbitrary (k,n)-threshold scheme can be achieved with no more than two single-mode squeezers.
