Conditional Generation of Optical Schrödinger Cat States
Given a source of two coherent state superpositions with small separation measurement it is possible to conditionally prepare a symmetrically placed superposition ofcoherent states around the origin of the phase sp...

Phase properties of the superposition of squeezed and displaced number states
The phase properties of the superposition of squeezed and displaced number states are examined in the framework of the Pegg-Barnett formalism. Moreover, amplitude squeezing and phase squeezing are discussed....

Slowing Quantum Decoherence by Squeezing in Phase Space
, these states quickly lose their nonclassical features and the associated negative oscillations of their Wigner function. However, by squeezing the superposition states coherent-state superpositions throu...

Optical Synthesis of Large-Amplitude Squeezed Coherent-State Superpositions with Minimal Resources
the quantum state engineering of heralded optical coherent-state superpositions. This scheme relies on a two-mode squeezed state, linear mixing, and a n-photon detection part of the targeted state. In the...

Amplification of Schrödinger-cat state: distinguishability and interference in phase space.
Amplification and cloning of the Schrödinger-cat state (even coherent/state superposition) in the optical nondegenerate parametric amplifier are analysed. In the long-time limit, distinguishability and interference in the m...

Phase properties of superposition of pair-coherent states.
We discuss the phase properties of the superposition of pair-coherent states on the framework of pegg-Barnett formalism. We show that even-pair-coherent states can map onto odd-pair-coherent states and vice versa t...

Quantum properties of a superposition of squeezed displaced two-mode vacuum and single-photon states
In this paper, we study some quantum properties of a superposition of displaced squeezed two-mode vacuum and single-photon states, such as the second-order correlation function, the Cauchy-Schwarz inequality, quadrature squeezing, q...
