Query: Arbitrary perfect state transfer in $d$-level spin chains   We exploit a ferromagnetic chain of interacting $d$-level ($d>2$) particles
for arbitrary perfect transfer of quantum states with $(d-1)$ levels. The
presence of one extra degree of freedom in the Hilbert space of particles,
which is not used in encoding, allows to achieve perfect transfer even in a
uniform chain through a repeated measurement procedure with consecutive single
site measurements. Apart from the first iteration, for which the time of
evolution grows linearly with the size of the chain, in all other iterations,
the evolution times are short and does not scale with the length. The success
probability of the mechanism grows with the number of repetitions and
practically after a few iterations the transfer is accomplished with a high
probability.
