Abstract

 Benefited from the technology development of controlling quantum particles and constructing quantum hardware, quantum computation has attracted more and more attention in recent years.  This talk will give an introduction of quantum computing and its applications in network optimization.  We first introduce the basics of quantum computing and what quantum parallelism is.  Second, we will discuss the adiabatic quantum computing math model and one real implementation, Quadratic Unconstrained Binary Optimization (QUBO) on D-wave quantum annealer.  Then we propose a hybrid quantum Benders’ decomposition algorithm for joint quantum and classic CPU/GPU computing.  Finally, we will discuss how our proposed framework can be employed in 6G network optimization, smart grid, and machine learning, as well as other quantum techniques such as Quantum Approximate Optimization Algorithm (QAOA).
