Quantum walks differ from classical ones in two main respects: firstly, although the dynamics are still linear, they are described with respect to probability amplitudes (complex numbers whose squared absolute values sum to 1), not probabilities (real numbers that sum to 1); and secondly in order to ...

Such a path is not necessarily the trajectory of any carrier in the network because bits on different carriers interact and can exchange information ...
