Engineering squeezed states in high-Q cavities
While it has been possible to build fields in high-Q cavities with a high
degree of squeezing for some years, the engineering of arbitrary squeezed
states in these cavities has only recently been addressed [Phys. Rev. A 68,
061801(R) (2003)]. The present work examines the question of how to squeeze any
given cavity-field state and, particularly, how to generate the squeezed
displaced number state and the squeezed macroscopic quantum superposition in a
high-Q cavity
Concentração de N, P e K na parte aĂŠrea de plantas de crisântemo cultivadas em vaso, em ambiente protegido sob nĂveis de condutividade elĂŠtrica.
O presente trabalho foi desenvolvido com o objetivo de avaliar os efeitos de nĂveis de condutividade elĂŠtrica, em cultivo protegido como meio de indicar a melhor concentração de sais a serem aplicadas Ă s plantas de crisântemo de forma a suprir a demanda de N, P e K. O experimento foi conduzido no municĂpio de Paranapanema (Holambra II), Estado de SĂŁo Paulo..

Teleportation of a Zero-and One-photon Running Wave State by Projection Synthesis
We show how to teleport a running wave superposition of zero- and one-photon
field state through the projection synthesis technique. The fidelity of the
scheme is computed taking into account the noise introduced by dissipation and
the efficiency of the detectors. These error sources have been introduced
through a single general relationship between input and output operators.Comment: 11 pages, 1 figur
Squeezing arbitrary cavity-field states through their interaction with a single driven atom
We propose an implementation of the parametric amplification of an arbitrary
radiation-field state previously prepared in a high-Q cavity. This nonlinear
process is accomplished through the dispersive interactions of a single
three-level atom (fundamental |g>, intermediate |i>, and excited |e> levels)
simultaneously with i) a classical driving field and ii) a previously prepared
cavity mode whose state we wish to squeeze. We show that, in the adiabatic
approximantion, the preparation of the initial atomic state in the intermediate
level |i> becomes crucial for obtaing the degenerated parametric amplification
process.Comment: Final published versio
