- Abstract
When the first AT&T satellite was launched in 1962 no one would have guessed that satellites would once become part of our everyday lives. Since services (inter-network communication, cellular, television signals) and devices (such as GPSs) have become widely available, the importance of satellites greatly increased and the need for efficient communication also arouse. Quantum computing has an even shorter history than satellites. From the engineering point of view, a quantum computing system may represent the highest level of information processing–a system where the physical layer is based on quantum mechanics. Although quantum computers are not to exist in the near future, the results of quantum computing are unquestionable: teleportation, search in an unsorted database, practically unbreakable key distribution and many more.
Previous studies show that it is worthwhile to mix satellite communication (a profitable business) and quantum computing (a new technologies). We developed a quantum channel model for satellite communication which can be useful both for satellite-satellite and earth-satellite communication. Nowadays different research projects demonstrate that quantum computing based satellite-communication could be a useful application in a couple of years. Quantum based systems can be important part of future telecommunications because their safety and effectiveness.
Although there are recent studies about the physical solutions of the quantum-based communication, it is worth to examine the efficiency of this type of communication. Our primary goal is to create a quantum computing based redundancy free error correction method that can be used over long distance aerial communication (such as earth-satellite). The initial problem to solve is the following: how to send certain amount of quantum bits over a noisy quantum channel, to provide error correction. This method could be very useful in the long-distance aerial communication, because there would be no need to use redundant error correction codes as nowadays. This way the effective capacity of the satellite link would also be increased.
In this paper we present a theoretical study, where the above described communication method is detailed. We introduce some quantum computing based error correction methods in satellite communication. We present channel models, where the error correction can be applied. An accuracy analysis for these models is also presented.
By applying this model to aerial communication it is possible to create a system where the channel usage is more efficient than in classical cases. This is a crucial requirement of modern telecommunication systems, as efficiency affects the profitability of a certain service and so the entire system’s success may depend on it.
