The future of wireless communication is being shaped by the potentials of 6G networks, which promise faster speeds, lower latency, and more reliable connectivity to support an array of advanced applications, from autonomous vehicles to smart cities. However, the complexity of these networks poses significant challenges in terms of real-time optimisation, energy efficiency, and security. At the London Digital Twin Research Centre (LDTRC), we are exploring cutting-edge research that combines Quantum Computing (QC) and Digital Twin (DT) technologies to address these challenges in Open Radio Access Network (O-RAN) architecture.
O-RAN is an emerging framework that enables a flexible, cost-effective, and open approach to managing wireless networks. Unlike traditional telecom architectures, O-RAN is based on modular, disaggregated components that can be sourced from multiple vendors, increasing adaptability and innovation. However, this modularity also introduces challenges in coordinating real-time operations, optimising resources, and safeguarding data security across diverse systems.
DTs are virtual models that mirror the physical components of a network, allowing for real-time monitoring, simulation, and optimisation. They enable network operators to test “what-if” scenarios, optimise configurations, and predict potential issues without disrupting live operations. When enhanced by QC, DTs become even more powerful, capable of running multiple complex simulations simultaneously and solving optimisation problems at unprecedented speeds.
At LDTRC, we are now leading two projects that explore the integration of QC and DT technologies into O-RAN:
-
- Exploring the concept of QC-Based Digital Twin for O-RAN:We will study and explore the concept of QC-Based DT for O-RAN, with collaborations between partners from the UK and India. Learn more about the project here.
- Quantum-Enhanced Digital Twin for Secure Open RAN: This collaborative effort with researchers from the UK and Japan explores deeper how Quantum Computing can amplify the capabilities of Digital Twins in O-RAN. By using QC’s computational power, the project seeks to optimise network performance and enhance efficiency. A real-world case study will demonstrate how QC-assisted DTs can transform O-RAN operations, providing tangible benefits for network operators and end-users alike.

These projects highlight LDTRC’s commitment to addressing the most pressing challenges in next-generation telecommunications. By combining the strengths of Digital Twin and Quantum Computing technologies, we aim to deliver practical solutions for O-RAN that are scalable, efficient, and secure.
