    "abstract": "Selective truncation of Fock-state expansion of an optical field can be\nachieved using projection synthesis. The process removes predetermined Fock\nstates from the input field by conditional measurement and teleportation. We\npresent a scheme based on multiport interferometry to perform projection\nsynthesis. This scheme can be used both as a generalized quantum scissors\ndevice, which filters out Fock states with photon numbers higher than a\npredetermined value, and also as a quantum punching device, which selectively\nremoves specific Fock states making holes in the Fock-state expansion of the\ninput field.",
