7. Game Theory: With Quantum Mechanics, Odds Are Always in Your Favor

Vladimir Silva1 
This chapter explores two game puzzles that show the remarkable power of quantum algorithms over their classical counterparts:
  • The counterfeit coin puzzle: It is a classical balance puzzle proposed by mathematician E. D. Schell in 1945. It is about balancing coins to determine which holds a different value (counterfeit) using a balance scale and a limited number of tries.

  • The Mermin-Peres Magic Square game: This is an example of quantum pseudo-telepathy or the ability of players to achieve outcomes that would only be possible ...
