dc.description.abstract | Recent experimental advances have measured individual coin components in discrete time quantum walks,
which have not received the due attention in most theoretical studies on the theme. Here is presented a
detailed investigation of the properties ofM, the difference between square modulus of coin states of discrete
quantum walks on a linear chain. Local expectation values are obtained in terms of real and imaginary parts
of the Fourier transformed wave function. A simple expression is found for the average difference between
coin states in terms of an angle h gauging the coin operator and its initial state. These results are
corroborated by numerical integration of dynamical equations in real space. The local dependence is
characterized both by large and short period modulations. The richness of revealed patterns suggests that
the amount of information stored and retrieved from quantum walks is significantly enhanced ifM is taken
into account. | pt_BR |
