Resumo
In this paper we present a new quantum state of light, obtained from an asymmetric
superposition of coherent states in circular stationary mode. The generation of this
state was proposed and the experimental apparatus required is presented. General
expressions describing various properties (statistical distribution, variances, atomic
inversion, etc..) Were obtained for arbitrary generations. We observed how they
behave their properties by varying the phase between the components of superpo-
sition states. We show that the statistical properties do not fully characterize the
resulting state, showing different states with the same statistics. Alternative ways
to distinguish these states were considered. Based on quantum interference in phase
space, we show how we can generate an approximation of the number state N2 thru a process called "quantum sculpture,"and check the influence of the stage in
this process. Finally, we measured the classicalidade not analyze this state and its
representation in phase space.
