摘要

Quantum computing has a 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, O(n^1/2) search in an unsorted database, practically unbreakable key distribution and many more. Previous studies show that it is to mix satellite communication (a profitable business) and quantum computing (a new technology). 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). In this paper we present a theoretical study. The initial problem to solve is how to send certain amount of quantum bits over a noisy quantum channel, how to provide error correction. Solving this problem, the used 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.
