Time, Date, Location: 11:00, Friday, May 12, 2023, Brian Anderson Building Seminar Room
Abstract: Quantum detector tomography (QDT) is a fundamental technique used for calibrating quantum devices and performing various quantum engineering tasks. In this talk, we will first provide a brief introduction to quantum physics and quantum tomography. We will then propose a two-stage analytical algorithm in QDT. Using this algorithm, we will further investigate optimal and adaptive designs for probe states to enhance estimation accuracy. However, in practice, probe states are often limited, which is why we will also explore the use of regularization techniques to solve this problem.
