Query: The magneto-optics in quantum wires comprised of vertically stacked
  quantum dots: A calling for the magnetoplasmon qubits   A deeper sense of advantages over the planar quantum dots and the foreseen
applications in the single-electron devices and quantum computation have given
vertically stacked quantum dots (VSQD) a width of interest. Here, we embark on
the collective excitations in a quantum wire made-up of vertically stacked,
self-assembled InAs/GaAs quantum dots in the presence of an applied magnetic
field in the symmetric gauge. We compute and illustrate the influence of an
applied magnetic field on the behavior characteristics of the density of
states, Fermi energy, and collective (magnetoplasmon) excitations [obtained
within the framework of random-phase approximation (RPA)]. The Fermi energy is
observed to oscillate as a function of the Bloch vector. Remarkably, the
intersubband single-particle continuum splits into two with a collective
excitation propagating within the gap. This is attributed to the (orbital)
quantum number owing to the applied magnetic field. Strikingly, the alteration
in the well- and barrier-widths can enable us to customize the excitation
spectrum in the desired energy range. These findings demonstrate, for the very
first time, the viability and importance of studying the VSQD subjected to an
applied magnetic field. The technological promise that emerges is the route to
devices exploiting magnetoplasmon qubits as the potential option in designing
quantum gates for the quantum communication networks.
