Abstract
In the current scenario of information explosion, one of the growing concerns of scientists worldwide is to manage the information storage and transmission by realizing the novel and reliable means of secure communication of data and information. This is essential to avoid any threat of the breaching of secret information on the part of hackers during the communication. In this regard, in contrast to routine classical methods, state-of-the-art robust quantum methods of secure communication such as quantum cryptography and Internet of Things (IoTs) information via quantum coherence medium and quantum networking of IoTs are gaining immense interest. In this context, chiral atomic medium and 2D materials such as graphene have attracted tremendous research interest. This owes to their remarkable linear and nonlinear ultrafast response and tunable structural and optoelectronic properties, which have potential applications in quantum computing, quantum information processing, information storage, and secure communication of IoTs information. In this paper, we explore the potential of Landau-quantized graphene (LQG) for secure communication of IoTs information by investigating quantum coherence-based propagation of light and optical properties of LQG. We report on the tunable optical response of a newly-proposed four-level ladder-type LQG subject to a weak probe field in conjunction with two strong control fields. In particular, employing the density-matrix approach, we report on theoretical analysis of superluminal/subluminal and absorption-free light propagation via quantum coherence in view of tunable electromagnetically induced transparency. Based on the tunable optical response of LQG, we propose a quantum networking model for the secure communication of quantum information via IoTs quantum networking.
