This talk starts from the philosophy of telecommunications using the classical Shannon channel capacity by discussing all related elements of the capacity and followed by the method in brief to achieve capacity above 1 Tbps and the related constraints. This talk then moves to the case when the medium of transmission is extended to the quantum channel followed by the use of quantum bit (qubit) for both quantum communications and quantum-based security. The recent results of the study in the international telecommunication union (ITU) on International Mobile Technology (IMT)-2030 are also introduced, especially for the topics of artificial intelligence/machine learning (AI/ML) and quantum radio access networks and quantum key distribution. This talk then provides the basic concept of quantum communications/computing and AI/ML, such as the quantum circuit, quantum channels, and types of quantum error correction codes. This talk also reviews our current developed quantum channel coding schemes on the quantum [[5,1,3]] perfect codes based on the accumulator and the new proposed quantum [[12,2,4]] accumulator codes having higher qubit rate followed by their simulated and theoretical quantum word error rate (QWER) performances. Both codes are based on syndromes and belong to the class of non-Calderbank-Shor-Steane (Non-CSS) codes. This talk also discusses, in brief, the contribution of entanglement to the success of quantum multiple access channels, which is expected to be useful for Radio Access Networks (RAN). Finally, this talk closes the session with quantum physical layer security and shows an example of quantum key distribution (QKD) for communications between Alice and Bob and their measurements using quantum gates X and Z...
