Title: Open Quantum Systems in Quantum Computing

Abstract: Quantum dynamics in real-world scenarios seldom stand alone; they occur under the continuous influence of surrounding environments. One important example is the quantum computers' gate operations, which are subject to environment noise. This noise can subsequently deviate the intended outcomes by the quantum algorithm. Consequently, the dynamics of open quantum systems describes a broader range of problems than the conventionally known time-dependent Schrödinger equation. In this presentation, we will show how models for open quantum systems can be derived, and how they can be simulated on quantum computers.
