Let us assume for the moment that both Alice and Bob always push their buttons before interacting. The magical rule is that an Alice is allowed to interact with a Bob if and only if they jointly satisfy the conditions of the nonlocal box set out in Table 1 <https://www.mdpi.com/1099-4300/21/1/87/htm#table_body_display_entropy-21-00087-t001> . "For example, if Alice pushes button 1, she splits. Consider the Alice who sees green. Her system can be imagined to carry the following rule: You are allowed to interact with Bob if either he had pushed button 0 on his box and seen green, or pushed button 1 and seen red. Should this Alice ever come in presence of a Bob who had pushed button 1 and seen green, she would simply not become aware of his presence and could walk right through him without either one of them noticing anything. Of course, the other Alice, the one who had seen red after pushing button 1, would be free to shake hands with that Bob." "When they meet, the correlations they experience are simply due to the matching rule that determines which Alices are allowed to interact with which Bobs," Bruce -- You received this message because you are subscribed to the Google Groups "Everything List" group.
