Abstract
SUMMARYThe efficiency of medium access control strongly influences the performance of distributed wireless networks. Collisions in the channel and unused timeslots result in poor performance. On the other hand, quantum superdense coding proved that entanglement‐assisted quantum communications can improve the data transmission rates compared with classical systems. It allows sending two classical bits from one party to another in exchange of one quantum bit and a pre‐shared entangled Bell pair. This paper introduces a new protocol, which involves a modified version of superdense coding to medium access control of distributed communication systems. Using a pre‐shared entangled Bell pair and one classical bit, 2.5 classical bits can be transmitted in average between the parties in each timeslot. This means not only valuable increase in capacity, but the two‐way distributed operation opens new fields of investigation. Copyright © 2014 John Wiley & Sons, Ltd.
