In this talk, I will introduce the concepts of Clifford unitary dynamics and quantities measuring deviations away from such dynamics, also known as quantum magic. The talk consists of roughly two parts, with the first part introducing concepts such as Pauli strings, operator spreading and Clifford unitary circuits. The second part concerns possible measures of quantum magic, as well as our recent work exploring the spreading of quantum magic in doped Clifford circuits. Throughout the talk, I will connect the Clifford circuit setup to quantum many-body systems, such as Clifford points in various quantum spin models, analogy between Clifford and Gaussian fermionic dynamics, as well as the implication of injecting quantum magic on the thermalizing properties of higher-order observables.
