    "abstract": "In this paper we explore the possibility of fundamental tests for coherent\nstate optical quantum computing gates [T. C. Ralph, et. al, Phys. Rev. A\n\\textbf{68}, 042319 (2003)] using sophisticated but not unrealistic quantum\nstates. The major resource required in these gates are state diagonal to the\nbasis states. We use the recent observation that a squeezed single photon state\n($\\hat{S}(r) \\ket{1}$) approximates well an odd superposition of coherent\nstates ($\\ket{\\alpha} - \\ket{-\\alpha}$) to address the diagonal resource\nproblem. The approximation only holds for relatively small $\\alpha$ and hence\nthese gates cannot be used in a scaleable scheme. We explore the effects on\nfidelities and probabilities in teleportation and a rotated Hadamard gate.",
