Terahertz (THz) Quantum and Classical Systems Using SSPP-based Slow EM Waves
Abstract
Development of communication devices and supporting infrastructure aims at sustainability of constant increase of traffic through wireless protocols. Flexibility of wireless (smart) devices drives opening new applications and thus feeds the demand for even higher data transmission rates. This will inevitably lead to expansion of communication systems into the THz region of the spectrum of the electromagnetic (EM) field. One specific character of the THz communication infrastructure is the small size of cells, namely, THz nano-cells. This creates the context, within which development of the theoretical background for THz technologies must be considered. This is reflected in the proposed plan of research with the objective to develop novel types of THz quantum and classical devices: (i) development of THz implementation of quantum key distribution (QKD) protocols and (ii) developing classical THz ultra-high-speed (~100 Gbps data rate) interconnect technology for networking servers, memory racks, and I/O systems of supercomputers, datacenters, and cloud computers.We plan to fill the existing gap of QKD studies and to prove the possibility to implement continuousvariable (CV) QKD protocols for mobile communicating entities within small size cells utilizing THzrange frequencies. In order to implement such QKD devices, it is necessary to be able to efficientlycontrol and manipulate THz radiation within devices of size consistent with mobile usage. The mostpromising way to achieve this is to utilize spoof surface plasmon polaritons (SSPP), states of the EM field localized near a corrugated conducting surface. The SSPP flow is due to overlap of resonant modes within corrugations and, as a result: (i) SSPP are characterized by low group velocity yielding efficient flow management; (ii) relatively short structures are sufficient for varying SSPP properties in a wide range, thus relaxing significantly manufacturing requirements.
