Abstract
========
We derive an adiabatic technique that implements the most general SU(d)
transformation in a quantum system of d degenerate states, featuring a
qudit. This technique is based on the factorization of the SU(d)
transformation into d generalized quantum Householder reflections, each of
which is implemented by a two-shot stimulated Raman adiabatic passage with
appropriate static phases. The energy of the lasers needed to synthesize a
single Householder reflection is shown to be remarkably constant as a
function ofd. This technique is directly applicable to a linear trapped ion
system with d +1 ions. We implement the quantum Fourier transform
numerically in a qudit with d = 4 (defined as a quartit) as an example.
