讲座内容：

The most general evolutions of open quantum systems are described by completely positive and trace-preserving maps, also called quantum channels. In this talk, I will introduce our recent works that explore interesting physics and phenomena arising in sequential quantum channels, either without or with feedback control. In the former case without feedback control, I will discuss the construction of arbitrary projective measurements with repetitive generalized measurements, the prediction and observation of metastability in repetitive channels, the channel spectrum measurement and its application in quantum sensing. In the latter case with feedback control, I will discuss the channel-based framework for adaptive quantum phase estimation alogorithms, and its application to error detection of bosonic quantum error correction codes.
