Pengedaran kunci kuantum atau pengedaran kunci rahsia (SKD) telah dikaji untuk menyampaikan kunci rahsia untuk komunikasi selamat, yang keselamatannya terjamin secara fizikal. Untuk penggunaan praktikal, sistem sedemikian dikehendaki untuk ditindih pada sistem penghantaran berganda panjang gelombang sedia ada, tanpa menggunakan talian penghantaran khusus. Kajian ini secara analitik menyiasat kebolehlaksanaan skema SKD intensiti-modulasi/pengesanan arah (IM/DD) dipelbagaikan panjang gelombang dengan isyarat panjang gelombang-division-multiplexed (WDM) konvensional, mengenai cahaya hamburan Raman spontan daripada isyarat optik konvensional. Keputusan simulasi menunjukkan bahawa sistem IM/DD SKD tidak terdegradasi apabila ia ditindih pada sistem penghantaran WDM padat yang digunakan secara praktikal dalam jalur C, disebabkan ciri skema IM/DD SKD, yang menggunakan lampu isyarat dengan tahap keamatan. setanding dengan isyarat optik konvensional tidak seperti skim pengedaran kunci kuantum konvensional.

Abstract: Quantum key distribution or secret key distribution (SKD) has been studied to deliver a secrete key for secure communications, whose security is physically guaranteed. For practical deployment, such systems are desired to be overlaid onto existing wavelength-multiplexing transmission systems, without using a dedicated transmission line. This study analytically investigates the feasibility of the intensity-modulation/direction-detection (IM/DD) SKD scheme being wavelength-multiplexed with conventional wavelength-division-multiplexed (WDM) signals, concerning spontaneous Raman scattering light from conventional optical signals. Simulation results indicate that IM/DD SKD systems are not degraded when they are overlaid onto practically deployed dense WDM transmission systems in the C-band, owing to the feature of the IM/DD SKD scheme, which uses a signal light with an intensity level comparable to conventional optical signals unlike conventional quantum key distribution schemes.
