A team of physicists in Europe, led by Marcin Pawlowski, has proposed a way to use entangled quantum particles to improve the odds of winning in the game of bridge. As the team notes in their paper published in Physical Review X, their proposition appears to be the first example of using quantum enhancement of information transfer as it applies to a real-world (non-physics) application.
Entanglement is where pairs of quantum particles are generated where their quantum state is no longer defined independently—instead a quantum state comes to exist that defines them as a single unit. The team in Europe has taken this concept and applied it to the game of bridge, increasing the odds of winning by a pair of players that successfully employs the strategy they’ve devised.
Bridge is a card game played by teams of paired individuals—successful players learn to communicate meaningfully with one another to convey information each needs to improve their hand, without being specific—that’s against the rules.
