Large effects of boundaries on spin amplification in spin chains
Benoit Roubert, Peter Braun, Daniel Braun
We investigate the effect of boundary conditions on spin amplification in spin chains. We show that the boundaries play a crucial role for the dynamics: A single additional couplin…

Quantum Cloning without Interference
Benoit Roubert, Daniel Braun
We study the role of interference in the process of quantum cloning. We show that in order to achieve better than classical cloning of a qubit no interference is needed. In particu…
