Asymptotic Dynamics of Qubit Networks under Randomly Applied Controlled Unitary Transformations
Original language description
The asymptotic dynamics of many-qubit quantum systems is investigated under iteratively and randomly applied unitary transformations. For a one-parameter family of unitary transformations, which entangle pairs of qubits, two main theorems are proved. They characterize completely the dependence of the resulting asymptotic dynamics on the topology of the interaction graph that encodes all possible qubit couplings. These theorems exhibit clearly which aspects of an interaction graph are relevant and whichones are irrelevant to the asymptotic dynamics.
