Abstract: | By applying the bosonic creation operator to squeezed
vacuum states, this paper introduces a new kind of quantum states:
photon-added squeezed vacuum states. It also presents an
experimental approach to prepare these states, and investigates
their quantum statistical properties by the numerical method. The
results indicate that these states reveal some interesting
non-classical properties, such as anti-bunching effects,
squeezing effects and negativities of the relevant Wigner
functions. |
