Abstract
Most experimentally controllable quantum systems invariably interact with an external environment and need to be described by an open quantum system model. In this talk, I will introduce the fundamentals of open quantum system dynamics, as well as known results on their complexity classification. I will then present three results:
1. Simulatability phase transitions in continuous time open quantum system dynamics in Markovian many-body spin systems, and in bosonic systems.
2. A generalization of quantum stochastic calculus to non-Markovian systems, and its complexity classification.
3. Limitations of near-term quantum systems for solving classical optimization problems due to their interaction with the environment.
