“…The various imperfections and losses can be seen which reduce the success probability. Khanna et al [11] examined the distance and power allocation strategies for quantum limited FSO system and no direct line of sight path is assumed between source and destination; thus, various atmospheric losses and imperfections are considered. It has been observed for minimizing probability of error that either distance can be optimized for constant power allocation or power allocation can be done for minimum error probability.…”

The photodetection classical theory is generally applied to communication systems working under optical frequencies. The recent development of non-classical theory uses photodetection statistics which require use of quantum theory. The growing interest in quantum detection techniques used in optics-based systems led to the study of quantum-based approaches in optics for improvement of various factors such as bit error rate and to examine the similarities and differences between the classical and quantum theory of optical communication. It has been observed that quantum detection technique gives more than 5 dB improvement in SNR and about 2.5 dB improvement in receiver sensitivity. This increased power budget can be used to increase the link length.
