摘要：

In contrast to the classical protocol, when one can generate as many copies of a system as one wishes, the no-cloning theorem forbids the perfect cloning of quantum systems. In this paper we present a scheme that enables the imperfect non-optimal copying of a qubit and show how the two non-identical clones can be distributed to two spatially separated receivers with the help of a non-maximally entangled channel.
