Sebastian Diehl and Simon Trebst
Mon 14:00-15:30
seminar room E0.01 | Institute for Theoretical Physics (new building)
The seminar will start in the second week of the term on Mon April 14th, 2025.
Overview
The seminar is motivated by recent progresses in the field of quantum computing platforms and their ability to control, via digital quantum circuits, of the order of O(100) qubits. We will approach these systems from the perspective of open system dynamics, reflect on the role of measurement and decoherence in such complex quantum systems, and explore their possibility to create, manipulate and decode quantum many-body entanglement in a dynamical setting.
Prerequisites
For most talks previous attendance in the lectures on Quantum Field Theory or Quantum Computational Physics will be useful, almost none of the topics can be covered with a basic background in quantum mechanics only.
