Abstract
A new computational approach to quantum antennas based on first
principle open stochastic quantum dynamics.
We develop a general computational approach for the analysis and design
of quantum antenna systems comprised of coupled quantum dot arrays
interacting with external fields and producing quantum radiation. The
method is based on using the GKSL master equation to model quantum
dissipation and decoherence. The density operator of a coupled two-level
quantum dot (qbit) array, excited by classical external signals with
variable amplitude and phase, is evolved in time using a quantum
Liouville-like equation (the master equation). We illustrate the method
in a numerical example where it is shown that manipulating the phase
excitations of individual quantum dots may significantly enhance the
directive radiation properties of the quantum dot antenna system
