Temperature effects on quantum cloning of states and entanglement
arXiv:0704.1177 · doi:10.1016/j.physleta.2008.12.050
Abstract
Performances of the symmetric universal and phase-covariant cloning transformations and entanglement cloners -- qubit case -- are investigated when the initial state of the hardware or the original state to be cloned is weakly coupled to a thermal environment. Different behaviors of each of these transformations are analyzed and contrasted with the ideal cases.
