Noisy coupled qubits: Operator spreading and the Fredrickson-Andersen model
Noisy coupled qubits: Operator spreading and the Fredrickson-Andersen model
Conventional wisdom suggests that noise is antithetical to quantum entanglement. On the other hand, the evolution of a quantum system in the presence of classical noise is still unitary, so that entanglement may be present even if it is hard to detect in an average over noise trajectories. Here, the …
