Some bounds for quantum copying with multiple copies
A. E. Rastegin
We study the relative error of the state-dependent N=>L cloning. A copying transformation and dimension of state space are not specified. Only the unitarity of quantum mechanical t…

Some bounds for quantum copying
A. E. Rastegin
We propose new optimality criterion for the estimation of state-dependent cloning. We call this measure the relative error because the one compares the errors in the copies with co…
