The field of quantum information systems is complex and multi-disciplinary. The interrelated subject areas are all challenging enough to understand in the first place. Academics and other researchers are also taking several differing approaches to what is commonly called quantum computing. NTT Research Director of Strategy, Kei Karasawa, recently took some time out to provide readers of EE Times with a brief overview of trends at play in this fascinating area of research. Please take a look at the article, “Quantum Information Technologies: Approaches, Use Cases and Metrics.”
