Estimation and Control in Quantum World

Abstract:
Quantum information science has helped significantly enhance our understanding of nature and how it works. In particular, estimation of unknown parameters — a pivotal task in science and technology — has improved by considering quantum resources. Similarly, controlling systems towards their target configurations or dynamics is another essential task, where quantum information science comes starkly useful. In this talk, I shortly review some of the main ideas of quantum metrology and quantum control, and argue that how our improved ability to perform these two tasks (estimation and control) enables diverse applications.
