## Abstract An arbitrary quantum state cannot be “cloned” perfectly, i.e. reproduced with “fidelity” __F__ = 1 into __M__ > 1 states identical to the original by any conceivable physical device. The main root of this impossibility resides in the linearity of quantum mechanics. A second “quantum imp
