Unveiling the Quantum Information Scrambling in Open Systems

Researchers from UC Berkeley and Harvard University have developed a universal framework that describes how quantum information scrambles in open quantum systems. The framework focuses on the interplay between errors and the dynamics of operator size distributions, which determine how errors spread in the system. The researchers found that errors not only modify the behavior of information scrambling but also provide insights into the functional form of experiments, such as the Loschmidt echo. The framework has the potential to improve the interpretation of experimental data and may have implications for the classical simulation of open quantum systems.
