    "abstract": "We propose a scheme for generating the superposition and the entanglement of\nsqueezed vacuum states of electromagnetical fields. The scheme involves\nsingle-photon source, single photon detector, and cross Kerr nonlinearity. The\nKerr nonlinearity required for generating the superposition of squeezed vacuum\nstates is 1/2 of that required for generating the superposition of coherent\nstates. The proposal can also be extended to generate the entanglement states\nbetween two coherent states and that between one coherent state and one\nsqueezed vacuum state.",
