General quantum Chinos games
The Chinos game is a non-cooperative game between players who try to guess
the total sum of coins drawn collectively. Semiclassical and quantum versions
of this game were proposed by F. Guinea and M. A. Martin-Delgado, in J. Phys.
A: Math. Gen. 36 L197 (2003), where the coins are replaced by a boson whose
number occupancy is the aim of player's guesses. Here, we propose other
versions of the Chinos game using a hard-core boson, one qubit and two qubits.
In the latter case, we find that using entangled states the second player has a
stable winning strategy that becomes symmetric for non-entangled states.
Finally, we use the IBM Quantum Experience to compute the basic quantities
involved in the two-qubit version of the game
