The fast development of modern technology and networks creates countless new opportunities for the future world of infocommunication. A new way of thinking is starting to arise as the digital networks are taking over the place of the analog devices and all communication is becoming wireless. The world is more and more willing to change and that change introduces the future of quantum communications.

Although quantum mechanics has been a researched field of science since the earlies of the 20th century, quantum computing has been truly introduced only in the last few decades. The new possibilities this field is offering, such as quantum teleportation, searching in unsorted database and quantum parallelism, could make a revolution in the world of communication.

The purpose of my work was to study how the new aspects of quantum communications could influence the development of ad hoc network architectures. The non-deterministic behavior of the quantum world can be used in many ways to create a self-organizing and self-adaptive network and quantum teleportation makes it possible to transmit quantum messages with the use of EPR-pairs. Apart from these basic features of quantum communication, I used the so-called entanglement swapping in the developed network simulator to be able to maintain entanglement between two photons that share no past.
