Since July 2022 three more Recommendations were approved and in the Q16/13 Rapporteur Group Meeting (Geneva, 14 – 25 November 2022), Q16/13 has made progress of the work items as reported below. 1. The items approved after the July 2022 SG13 meeting The draft Recommendations ITU-T Y.3810, Y.3811, Y.3812 were approved. Draft Recommendation ITU-T Y.3810 (ex Y.QKDN_iwfr) “Quantum key distribution network interworking - framework” For quantum key distribution networks (QKDN), Recommendation ITU-T Y.QKDN-iwfr specifies framework of QKDN interworking (QKDNi). This Recommendation describes the overview of interworking QKDNs, the reference models, and the functional models of gateway functions (GWFs) and interworking functions (IWFs). The configurations for QKDNi are specified. Appendix I includes QKDNi with different key relay schemes. Draft Recommendation ITU-T Y.3811 (ex Y.QKDN-qos-fa) “Quantum key distribution networks - Functional architecture for quality of service assurance” This Recommendation specifies a functional architecture of QoS assurance for the quantum key distribution networks (QKDN). This recommendation first provides an overview of the functional architecture of QoS assurance for the QKDN. It then describes the functional architecture of QoS assurance which includes functional entities such as QoS data collection, data processing, data storage, data analytics, QoS anomaly detection and prediction, QoS policy decision making, and enforcement and reporting. Based on the functional entities described in the functional architecture, this Recommendation specifies a basic operational procedure of QoS assurance for the QKDN. Draft Recommendation ITU-T Y.3812 (ex Y.QKDN-qos-ml-req) “Quantum key distribution networks - Requirements for machine learning based quality of service assurance” This recommendation specifies high-level and functional requirements of machine learning (ML) based QoS assurance for the quantum key distribution networks (QKDN). This recommendation first provides an overview of requirements of ML based QoS assurance for the QKDN. It describes a functional model of ML based QoS assurance and followed by associated high level and functional requirements of ML based QoS assurance. And some use cases are described. 2. The items consented after the July 2022 SG13 meeting The following Recommendations were consented. Draft Recommendation ITU-T Y.3813 (ex Y.QKDN-iwrq) “Quantum key distribution networks interworking – functional requirements” in TD144-WP3 For quantum key distribution networks (QKDN), Recommendation ITU-T Y.QKDN_iwrq specifies functional requirements for QKDN interworking (QKDNi). This Recommendation describes the functional requirements for key management layer, QKDN control layer, and QKDN management layer, for interworking using gateway nodes (GWNs) and/or interworking nodes (IWNs). Draft Recommendation ITU-T Y.3814 (ex Y.QKDN-ml-fra) “Quantum key distribution networks - functional requirements and architecture for machine learning enablement” in TD145-WP3 QKDN is expected to maintain stable operations and meet the requirements of various cryptographic applications efficiently. Due to the advantages of machine learning (ML) related to autonomous learning, ML can help to overcome the challenges of QKDN in terms of quantum layer performances, key management layer performances and QKDN control and management efficiency. Based on the functional requirements and architecture of QKDN in [ITU-T Y.3801] and [ITU-T Y.3802], this recommendation is to specify one possible set of functional requirements and a possible architecture for ML-enabled QKDN (QKDNml), including the overview, the functional requirements, architecture and operational procedures of QKDNml. 3.

New work items agreed at the November 2022 Working Party 3/13 meeting Draft Technical Report ITU-T TR-QN-UC “Use cases of quantum networks beyond QKDN” in TD158-WP3 This Technical Report presents the use cases of quantum networks beyond QKDN under three categories as follows: - Use cases based on quantum information networks (QINs): use cases that depend on QIN to realize their function as for example, but not exclusive, to distributed quantum computing, distributed quantum sensing, quantum clock network, etc. - Use cases beneficial for classic networks: use cases that can provide additional functionality, new characteristics, or improved performance for classic ICT networks as for example, but not exclusive to, quantum random number generator (QRNG), quantum time synchronization (QTS), quantum cryptography beyond QKD, etc. - Use cases where the network plays an intrinsic role for the QIT application: use cases in which the QIT application is significantly defined or enhanced by the functionality provided by a QIN and/or a classical network and is beyond simple remote access of a QIT application via a classical network. Some examples include synchronization of quantum clocks, distributed QRNG beacons for smart contracting, etc. NOTE – QIN could be defined as any network that incorporates quantum communication technologies for the purpose of transporting quantum states. In particular, the content of this technical report includes use cases of quantum network beyond QKDN in various relevant fields of application and provides an analysis of their technical advantages, key enabling technologies, maturity and application prospects.
