Open Quantum System Theory

Synopsis

Open quantum theory research focuses on how a small subsystem interacts with a much larger environment. However, there are many open debates in this field: How do we define topological protection in an open system? Can we use the environmental coupling to autonomously operate on a state without using a measurement? Is there a universal description of an open system? In this talk, I explore how topology, steady states, and engineered dissipation reshape our understanding of quantum dynamics beyond the closed-system idealization.
