Consistency Tests of Classical and Quantum Models for a Quantum Annealer

Understand

Recently the question of whether the D-Wave processors exhibit large-scale quantum behavior or can be described by a classical model has attracted significant interest.

• In this work we address this question by studying a 503 qubit D-Wave Two device in the "black box" model, i.e., by studying its input-output behavior.
• Our work generalizes an approach introduced in Boixo et al.
