Quantum state complexity metrics, such as anticoncentration and magic, offer key insights into many-body physics, information scrambling, and quantum computing. Anticoncentration and equilibration of magic under dynamics of random quantum circuits oc

Dynamical phase transitions induced by local projective measurements have attracted a lot of attention in the past few years. It has been in particular argued that measurements may induce an abrupt change in the scaling law of the bipartite entanglem

Understanding how entanglement can be reduced through simple operations is crucial for both classical and quantum algorithms. We investigate the entanglement properties of lattice models hosting conformal field theories cooled via local Clifford oper

We introduce a nonstabilizerness monotone which we name basis-minimised stabilizerness asymmetry (BMSA). It is based on the notion of $G$-asymmetry, a measure of how much a certain state deviates from being symmetric with respect to a symmetry group

We explore to which extent it is possible to construct efficient classical simulation of quantum many body systems using a combination of tensor network methods and the stabilizer formalism. For this we study both quantum circuit and Hamiltonian dyna

We present a thorough investigation of non-stabilizerness - a fundamental quantum resource that quantifies state complexity within the framework of quantum computing - in a one-dimensional U(1) lattice gauge theory. We show how non-stabilizerness is

Magic, also known as nonstabilizerness, quantifies the distance of a quantum state to the set of stabilizer states, and it serves as a necessary resource for potential quantum advantage over classical computing. In this work, we study magic in a meas

Magic state resources or non-stabilizerness quantify the beyond-Clifford operations necessary for universal quantum computing. How rapidly are magic resources generated by generic many-body dynamics under constraints of locality? We address this prob

In this paper, we investigate the relationship between entanglement and non-stabilizerness (also known as magic) in matrix product states (MPSs). We study the relation between magic and the bond dimension used to approximate the ground state of a man

Nonstabilizerness, also known as ``magic'', stands as a crucial resource for achieving a potential advantage in quantum computing. Its connection to many-body physical phenomena is poorly understood at present, mostly due to a lack of practical metho
