Quantum theory generally does not predict the outcomes of individual measurements. We might be tempted to think that the individual outcomes are determined by hidden variables that quantum theory doesn't know about. This article uses simple examples with qubits to show that such a model would need to have a strange feature in order to reproduce quantum theory's predictions.
