  We study the electromagnetic form factors and tensor polarization observables
of the deuteron in the framework of the hard-wall AdS/QCD model. We find a
profile function for the bulk twist $\tau=6$ vector field, which describes the
deuteron on the boundary and fix the infrared boundary cut-off of AdS space in
accordance with the ground state mass of the deuteron. We obtain the deuteron
charge monopole, quadrupole, and magnetic dipole form factors and tensor
polarization observables from the bulk Lagrangians for the deuteron and photon
field interactions. We plot the momentum transfer dependence of the form
factors and tensor polarization observables and compare our numerical results
with those in the soft-wall model and experimental data.
