Abstract
|
|α, δθ, shifted in phase by π, the latter being introduced by Othman et al. as a new class of quantum
states attached to the simple harmonic oscillator and also generated via a Mach–Zehnder interferometer.
To gain an insight into the effectiveness of these states in quantum information theory, we present a
general analysis of nonclassical properties by evaluating the Mandel parameter, quadrature squeezing,
amplitude-squared squeezing, and the Wigner distribution function. We show that the factor δθ plays
an essential role in the nonclassical properties of these (anti-)symmetric superposed states. Finally,
we propose a theoretical scheme to generate introduced states within a cavity QED framework.
