Resilient Quantum Computation in Correlated Environments: A Quantum Phase Transition Perspective
... Connection to the AKP results.—In Ref. [8], a family of long-ranged noise models with interactions between qubits was studied. AKP considered a power law interaction between any two qubits at positions x1 and x2 of the computer with strength jx1 x2 j2 . Clearly, one could start from their noise ...
