Quantifying information scrambling via Classical Shadow Tomography on Programmable Quantum Simulators
Max McGinley, Sebastian Leontica, Samuel J. Garratt +2
We develop techniques to probe the dynamics of quantum information, and implement them experimentally on an IBM superconducting quantum processor. Our protocols adapt shadow tomogr…
