Magnetotransport in the quantum wires comprised of vertically stacked quantum dots: A calling for themagnetoplasmon qubits

We report on a periodic system of vertically stacked InAs/GaAs quantum dots (VSQD) subjected

to a two-dimensional confining harmonic potential and a magnetic field in the symmetric gauge. Given

the tiny length scales, adequate lateral confinement, and strong vertical coupling involved in the

experiments, the VSQD system has become known for mimicking the standard semiconducting quantum wires.

An exact analytical diagnosis of the problem allows us to show the system's direct relevance to the

physics of musical sounds, magnetization, magnetotransport, and the designing of the optical amplifiers^1-4.

The results suggest making the most of the system for applications in single-electron devices and quantum

state transfer in the quantum computation. 1. M.S. Kushwaha, J. Chem. Phys. 135, 124704 (2011); 2.
