On nonlinear evolution and supraluminal communication between finite quantum systems
M. Ferrero, D. Salgado, J. L. Sanchez-Gomez
Abstract
We revise the 'no-signaling' condition for the supraluminal communication between two spatially separated finite quantum systems of arbitrary dimensions, thus generalizing a similar preceding approach for two-qubits: non-linear evolution does not necessarily imply the possibility of supraluminal communication between any sort of finite quantum systems.
