“…One possible way to produce coherent states is to use a subwavelength laser beam 54 directly focused at the gap of an optical nanowire antenna. 55 The antenna excited in this way was shown to exhibit a stable radiation pattern, and its efficiency and gain characteristics were found to improve with optimization of the antenna shape. 56 Since intense subwavelength beams are locked up with the resonant plasmonic surface waves excited by the laser field, this structure may provide a practical realization of an externally controlled classic current shielded from photon back-reaction, 56 leading then to the radiation of coherent states.…”

We develop a general mathematical formalism and computational method suitable for analyzing the performance of quantum communication systems utilizing coherent radiation states (Schrodinger states). The key motivation is to demonstrate how the analysis and design of quantum communication systems may benefit from the integration of the physical structure (here, the optical quantum coherent state) with the quantum signal processing aspects (here, quantum estimation and prediction theory). As an application, we show how the quantum-electromagnetic signature of optical radiation emitted by quantum antennas, the Schrodinger's coherent state structure, may be exploited to jointly design the transmitter and receiver of a K-ary digital communication link. We present a concrete example comprised of a quantum quadrature-amplitude modulation (QAM) system (with K = 64), including a complete description of the required general design principles developed from quantum mechanics and the quantum antenna's radiated coherent state structure. The simulation results illustrate improvement in spectral efficiency due to the use of K = 64 over smaller values of K. We also compare the quantum antenna-based link performance with classical QAM utilizing classical antenna-based communication systems and report superiority of the quantum link over the classical version. To provide for security protection, our system is equipped with a quantum encryption protocol for quantum key distribution, and a demonstration of the complete quantum QAM system with encryption is presented. The main message of the article is the fruitfulness of incorporating a multidisciplinary approach to our thinking about electromagnetic wireless systems through the joint deployment of electromagnetic, quantum, and communication theories in the design and development process of current and future advanced technologies.

“…It is a promising field in experimental optics and optical electronic devices; e.g., some researchers have reported the experimental demonstration of nanometer-scale lasers generating a 100 times smaller than the diffraction limit [16]. To the best of our knowledge, illuminating a nanoantenna by a subwavelength laser has not been discussed in the literature so far, aside from our recent brief report [17]. In this paper, a detailed and full investigation arXiv:1911.13131v1 [physics.optics] 29 Nov 2019 of how to model and design transmitting nanoantenna using a subwavelength laser excitation method is provided.…”

Nanoantennas are efficient devices exhibiting large confined electric field enhancements. So far, they have been extensively researched mainly in the receiving mode, which means that the illuminating field is essentially a plane wave. In this paper, we consider the problem of designing an efficient and highly directive transmitting Nanoantenna where the system is energized by a non-plane wave field, a subwavelength laser excitation. Including short-wavelength components allowed us to achieve a 200-nm spot radius, which is a quarter of its incident wavelength (800 nm). Near-and far-field antenna quantities are introduced and calculated using an efficient full-wave multiphysics solver. A nano-scale optical antenna is then presented with optimized dimensions and material settings. Various design curves and insights are also discussed in connection with how issues such as how to define efficiency and determine whether the system is radiating properly.
