Abstract

We give an alternative formulation of the no-cloning theorem that applies to\nharmonic oscillator coherent states. It says that em unknown single harmonic\noscillator coherent states can not be em amplified. Conversely it says that\n em known harmonic oscillator coherent states can be directly amplified\nthrough an universal unitary process. It is also shown that such a formulation\nis needed for the consistency of em information cloning proposed by us long\nago.\n
