Noise in Quantum Systems

Definition

Noise in quantum systems refers to unwanted disturbances that can affect the coherence and performance of quantum states, leading to errors in computations and information processing. This interference arises from various sources, including environmental factors, imperfect measurements, and operational inaccuracies, which challenge the delicate nature of quantum states. Understanding and mitigating noise is crucial for the development of reliable quantum technologies, particularly in models designed for generative tasks like Quantum GANs.
