Age of Information for Quantum Communication channels with Monogamy of Entanglement

Communication systems play a key role in today’s society due to the enormous flow of information that we share daily in every aspect of our lives. Among others, there is a continuous flow of information regarding status updates that has to be shared to assure the well-functioning of multiple devices. It is, therefore, mandatory to ensure that this information can be shared as fast as possible, and without the risk of being lost or accessed by the wrong recipients. Particularly, eavesdropping is a matter of great importance. In this thesis work, we analyze an information update system, where the communication between a sender and a receiver is taking place through quantum channels, and we consider the presence of two malicious eavesdroppers. To tackle this problem, we employed game theory as a modeling approach and utilized the computational tool MATLAB to identify the Nash equilibrium points. Finally, we analyze the transmission rate and eavesdropper probability, together with the total utility and the price of anarchy for the different Nash equilibrium points and for different cost values.
