Typical Mixing and Rare-State Bottlenecks in Open Quantum Systems
Caisheng Cheng, Ruicheng Bao
Mixing in open quantum systems is often summarized by a single worst-case time, even though that benchmark can be set by exponentially rare initial states. We show that for broad u…

Physically natural metric-measure Lindbladian ensembles and their learning hardness
Caisheng Cheng, Ruicheng Bao
In open quantum systems, a basic question at the interface of quantum information, statistical physics, and many-body dynamics is how well can one infer the structure of noise and…
