TL;DR: In this article , the authors report the measurement of logical qubit performance scaling across several code sizes, and demonstrate that their system of superconducting qubits has sufficient performance to overcome the additional errors from increasing qubit number.

TL;DR: In this article, the authors describe the quantum information propagation process in quantum systems, which can spread initially localized quantum information into the exponentially many degrees of freedom of the entire system, known as quantum quantum information dissemination.

TL;DR: In this article, the Fermi-Hubbard model is simulated using 16 qubits on a digital superconducting quantum processor, and the authors observe separations in the spreading velocities of charge and spin densities in the highly excited regime.

TL;DR: A reset protocol is reported that returns a qubit to the ground state from all relevant higher level states and finds lower rates of logical errors and an improved scaling and stability of error suppression with increasing qubit number.
