摘要：
Conditions to generate high-purity entangled vacuum-evacuated coherent states (vertical bar 0 > vertical bar alpha >(0)- I- alpha >(0) vertical bar 0 >) were studied for two cascade-placed beam splitters, with one squeezed state input and two coherent state inputs whenever a single photon is detected. Controlling the amplitudes and the phases of the beams allows for various amplitudes of the vacuum-evacuated coherent states (vertical bar alpha >(0) = vertical bar alpha >- e-vertical bar alpha vertical bar(2)vertical bar 0 >) up to alpha = 2.160 to be manipulated with high-purity.
