Generation of Nonclassical Optical States and Entangle Statesby Using Beam Splitters and Conditional Measurement
Yun‐Jie Xia · Acta Sinica Quantum Optica · 2004
Any number state is truncated from the beam splitters' input coherent state by the conditional measurement if the coherent state and single-number state are the beam splitters' input states .The various properties of this kind of the truncated optical field state are studied, the results show that the output states truncated with vacuum state and the single-number state have nonclassical properties of squeeze and sub-Poissonian distribution. The output state has quantum entangle property if the input state of the beam splitter are the former truncated state and vacuum state, so we generate quantum entangle states and verify the nonclassical properties of the truncated state at the same time.
