Dynamics of many-body open quantum systems – theoretical description, simulatability, and technological applications

Rahul Trivedi


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.


Rahul Trivedi is a postdoctoral scholar at the Max Planck Institute of Quantum Optics, and Max Planck Harvard Research Center for Quantum Optics. His current research focuses on developing tools for simulating many-body open quantum systems, using tools from quantum information theory and quantum complexity theory to understand their limitations and develop hardware proposals for next-generation quantum information. technologies
