Open quantum systems in quantum computing

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. This presentation will address the following questions
* What are the most efficient methods to simulate the dynamics of an open quantum system?
* How can quantum channels be harnessed to depict non-Markovian quantum dynamics?
* Is it possible to leverage these simulation methodologies to scale the noise within a quantum circuit?
