Abstract: Quantum behaviour in electrical circuits Bell inequalities provide a quantitative measure that can distinguish classically determined correlations from stronger quantum correlations. Experiments on microscopic systems such as atoms and photons strongly favour the quantum description, but there has been no Bell test in a solid-state system. This paper reports clear evidence for violation of a Bell inequality (and thus quantum behaviour) in a macroscopic electrical circuit consisting of superconducting phase qubits.
