The scientists were able to change the new version of the game that uses black and white figures, to the level of a quantum state. They replaced the black and white elements with pairs of entangled photons. And the resulting state was called a quantum experiment. According to the experts, this work could herald a completely new phase of games that are based on quantum physics.
In traditional games, players have to conquer board territories by taking other people's pieces. It is a complex intellectual game, but it is governed by simple rules, and its mechanism made it the main target of the researchers.
The quantum version uses entangled photons, which brings out new levels of difficult and random situations. The differences between the players lie in the characteristics of the photon - whether it is entangled by another or not. When a player uses two photons, they are in a state of entanglement until the other is next to one of them.
But while they are entangled, none of the photons can be captured by another player. But another player does not know about the state of the photon until making an attempt to capture it, for which the use of random elements and various tricks are encouraged.
Such features of the game in a quantum state have been studied by researchers from China. They used the board game 'go' as their main example. After successful experiments, the scientists recognized that their development could become the basis for the creation of other quantum games.
The go game is a bit like checkers. It is played on a board using black and white pieces. At first sight, the game seems simple, but a closer look reveals that a high level of play can arise from complexity. The difficulty level has been increased by the addition of a quantum element.
