Continuous operations on non-Markovian processes
Fabio Costa, Jing Yang
Continuous measurements are central to quantum control and sensing, yet lack a model-independent operational description that can be applied to arbitrary non-Markovian processes wi…

Lossless Postselected Quantum Metrology with Quasi-pure Mixed States
Jing Yang
Postselection can compress the metrological information and improve sensitivity in the presence of certain types of technical noise. Postselected quantum metrology with pure states…

Theory of Compression Channels for Postselected Quantum Metrology
Jing Yang
Postselected quantum metrological scheme is especially advantageous when the final measurements are either very noisy or expensive in practical experiments. In this work, we put fo…
