Magic spreading in doped Clifford circuits — •Jiangtian Yao and Pieter W. Claeys — Max Planck Institute for the Physics of Complex Systems

We study the spreading of magic, or nonstabilizerness, in Clifford circuits with doping by non-Clifford gates. We characterize the spatial extent of magic in classes of Clifford circuits where the growth behavior of entanglement entropy and operator strings are known. The dynamics of magic spreading in such circuits is compared to that of entanglement entropy, and quantitative measures for longer-ranged magic are also explored.

Keywords: Clifford circuits; quantum circuits; magic; nonstabilizerness; quantum chaos
