Abstract

Quantum communication is a theory based on the idea that quantum states can be transferred from one place to another. This theory has several advanced features. Specifically, it has high security, low time cost and low power overhead. Quantum information can make the execution of tasks much less efficient. However, much research has been done to achieve quality control by proposing utterly new security algorithms. The modulation and demodulation tasks of QC have not been sufficiently studied. Therefore, the modulation and demodulation methods are systematically summarised and analysed according to the two types of "signal type" and "modulation method type", respectively. In summary, PSK modulation outperforms OOK modulation in SRM-based multi-user detection schemes. The serious shortcomings of generalised secrecy modulation in terms of information-theoretic security mean that the security of GCM is not good. Moreover, there are many practical problems still required to be addressed. For example, the computational complexity characterisation and optimisation with correlation type receivers. Especially for ultra-high SE improvement have a large N parameter. Switching the slits at a reliable and efficient pace is a challenge. The high SE reduce the importance of speed. The complexity of the ML decoder combing with the joint modulation/coding should be explicitly modelled. Finally, the design of optical set-up in combination with amplifier structures recovering the loss due to MPD design.
