Quantum physics: A grip on misbehaviour : Nature : Nature Publishing Group
Interesting discussion of how to tell apart classical and quantum systems using Bells inequality. The basic idea is finding more correlated events between two separate
systems than one might expect classically were they are decoupled. This implies that there is a quantum characteristic to the system. This fact can be exploited to measure the degree to which two systems are behaving as a “quantum unit” in relation to cryptographic applications and large-scale quantum
computation.
