Operator space fragmentation in perturbed Floquet-Clifford circuits
Operator space fragmentation in perturbed Floquet-Clifford circuits
Floquet quantum circuits are able to realise a wide range of non-equilibrium quantum states, exhibiting quantum chaos, topological order and localisation. In this work, we investigate the stability of operator localisation and emergence of chaos in random Floquet-Clifford circuits subjected to unitary perturbations which drive them away from the Clifford …
