Decoherence is a subject of great importance in quantum mechanics, particularly in the
fields of quantum optics, quantum information processing and quantum computing. Quantum …

The reconstruction of quantum states of electromagnetic fields is an active research field in
modern physics. This paper presents a brief review on this issue. Our review includes the …

Neste trabalho investigamos a preparaçao de estados nao-classicos do campo
eletromagnetico quantizado, confinado em cavidade microonda, ou em modo viajante; a …

We consider experimental routes to determine the nonclassical degree of states of a field
mode. We adopt a distance-type criterium based on the Hilbert-Schmidt metric to quantify …
