Interaction in quantum systems can spread initially localized quantum information
into the many degrees of freedom of the entire system. Understanding this process,
known as **quantum scrambling**, is the key to resolving various conundrums in physics.

In arXiv:2101.08870, we experimentally investigated
the dynamics of quantum scrambling on a 53-qubit quantum processor. By measuring
the time-dependent evolution and fluctuation of out-of-time-order correlators (OTOCs),
signatures of both mechanisms associated with quantum scrambling, *operator spreading*
and *operator entanglement*, were experimentally observed.

This documentation shows how to build quantum circuits used in this experiment and run them to reproduce results in this publication.
