We look at a paper by Nicolas Gisin

which considers a variation of the superluminal (faster-than-light) communication setup where quantum measurements are made of an entangled pair of qubits. In this paper, an ensemble of qubits is considered, so that a macroscopically large signal is obtained on Bob's side. This reformulates a famous tension that exists between relativity and quantum mechanics, where it is consistent, but for entirely different reasons.
