Quantifying operator spreading and chaos in Krylov subspaces with quantum state reconstruction
Abinash Sahu, Naga Dileep Varikuti, Bishal Kumar Das +1
We study operator spreading in many-body quantum systems by its potential to generate an informationally complete measurement record in quantum tomography. We adopt continuous weak…
