Arbitrarily many independent observers can share the nonlocality of a single maximally entangled qubit pair
Peter J. Brown, Roger Colbeck
Alice and Bob each have half of a pair of entangled qubits. Bob measures his half and then passes his qubit to a second Bob who measures again and so on. The goal is to maximize th…
