As a result, land was concentrated in the hands of relatively few wealthy, plantation-owning families, and production was largely dependent on slave labor. The intermixing of these Europeans and Blacks, as well as the native
Quantum refereed game refereed game consists of an n-turn referee along with functions formula_17 that maps each measurement output formula_18 to Alice's and Bob's pay-off. Individual quantum refereed games may place specific restrictions on strategies Alice and Bob can choose from. For example, in nonlocal games and pseudo-telepathy games, Alice and Bob are allowed to share entanglement but are forbidden from communicating. In general, such restrictions may not apply in quantum refereed games. Similar to a classical zero-sum game, a zero-sum quantum refereed game is a quantum refereed game with the additional constraint formula_19. It is natural to assume Alice and Bob play
