摘要：

We study the phase properties of quantum superpositions of two coherent states (Schrodinger-cat states) amplified by phase-sensitive (squeezed) amplifiers. We show that a phase-sensitive amplifier with a properly chosen phase can preserve the phase distribution of the Schrodinger-cat-state input.
