To increase the channel capacity and security, the multiplexer is operated incorporating a quantum processing unit via an optical multiplexer. The transmission part can be used to generate the high capacity quantum codes within the series of microring resonators and an add/drop filter. The receiver part can be communicated by using the quantum key (quantum bit, qubit) via a wavelength router and quantum processors. The reference states can be recognized by using the cloning unit, which is operated by the add/drop filter, where the communication between Alice and Bob can be performed. Results obtained have shown that the correlated photons can be generated and formed the entangled photon pair, which is allowed to form the secret key between Alice and Bob. In application, the embedded system within the computer processing unit is available for quantum computer. Furthermore, such a concept is also available for internet application via hybrid communications, for instance, wire/wireless, satellite, which can be used to form the internet security.

“…However, the security technique known as quantum cryptography has been widely used and investigated in many applications [1–3]. Recently, Suchat et al [4] have reported the interesting concept of continuous variable quantum key distribution (QKD) via a simultaneous optical‐wireless up–down link system, where they have shown that the continuous variable quantum key could be performed via chaotic signals generated in a nonlinear microring resonator system with appropriate soliton input power and microring resonator parameters. They have also shown that the different time slot entangled photons can be formed randomly and can be used to select two different frequency bands for up–down link converters within a single system.…”
