Two-mode squeezed states in the q-deformed Pegg-Barnett Fock space | Yidan Wang

8 Dec 2012 | Abstract: | We study the coherent state and two-mode squeezed state in the q-deformed
Pegg-Barnett(PB) formalism. We show that when the truncation of the Fock space
S is large enough, the phase properties of the q-deformed PB coherent state
approach that of the undeformed PB coherent state. We also investigate the
entanglement properties of the two-mode squeezed states in both the q-deformed
and undeformed PB Fock space with the real squeezing parameter r. We see that
if S is sufficiently large, the conventional two-mode squeezed states can be
approximated with the PB (deformed and undeformed) states for arbitrary r.
However, the value of S required increases more rapidly with the q-deformed PB
states than the PB states as a function of r. | Source: | arXiv, 1212.1794 | Services: | Forum | Review | PDF | Favorites |
