Introduction :Molecular communication is a natural communication method used by living organisms (e.g., pheromone communication) and is predicted to become a portable method for future nanodevices. The concentration of a molecule in the close vicinity of the receiver may be used to sense the transmitter of the molecular bit being sent. Quantum communication is based on the transfer of entangled pairs from one location to another, using exchange, repetition, and purification. Quantum interference or quantum parallelism gives us enormous computational power, especially in source coding, where information about the entire content is needed instead of individual inputs. FRET is a non-radiative energy transfer process between fluorescent molecules based on dipole-dipole interactions of the molecules. Energy is rapidly transferred from a donor to an acceptor molecule in close proximity, such as 0 to 10 nm, without the emission of a photon. Low dependence on environmental factors, control of its parameters, and relatively wide transmission range make FRET suitable for high-speed nanoscale communication channels.The TN nanotransmitter and RN electromagnetic receiver must be able to perform operations such as baseband processing , frequency conversion, filtering, and amplification of the signals it sends or those that reach the nanoantenna from free space. Given that the nanoantenna will oscillate at terahertz frequencies, it is necessary to use FET RF transistors that are capable of operating at this high frequency . Several transistors have been developed and introduced in this field. At lower frequencies, nanodevices are able to communicate over longer distances, but the efficiency of nanodevices is expected to be very low in this case. Therefore, nanosensors do not communicate at MHz frequencies, and higher energy waves are required to control a large number of nanodevices over a very wide area. For this reason, nanodevices communicate at frequencies of about 1.0 to 10 terahertz. Due to the severe limitations of nanodevices in terms of size and energy, the generation of high-power signals at terahertz frequencies is not practical. Therefore, classical communication patterns based on continuous signal communication cannot be implemented and for WNSNs, short-pulse modulation techniques in the time domain (OOK-TS: Keying Off-On) are used. These techniques are used especially in cases such as extracorporeal disease diagnosis systems and targeted drug delivery in the body as well as the nano-Internet of Things. Waves as information carriers are similar to classical communications. However, due to the severe shortage of resources and quantum effects of materials, classical methods cannot be directly applied in the nano-domain. Hence, it is necessary to use new materials and techniques.
