Entangled state representation for describing both squeezing and entanglement involved in the parametric down-conversion process
Hong-Yi Fan, Nian-Quan Jiang · Physica Scripta · 2010
By constructing a new orthogonal-complete quantum mechanical entangled state representation, we show that it can provide us with a combinative view of both squeezing and quantum entanglement involved in the parametric down-conversion process. The two-mode Wigner operator in this representation is also found.
