Physics developed the idea of quantum "honest" casino. According to RIA "news", Specialist from the University of Bristol Jeremy O’Brien stated that the main online casino problem is that in this area there is no possibility to check for honesty both the player and the organizer itself. According to a scientist, now it is possible to create a committed casino perfect in the honesty. The essence of the protocol developed by scientists is that it allows the game without the participation of a third party. The main idea is enclosed in equal capabilities of controlling the game process and checking the opponent for honesty for both casino and player. Namely, in this scheme, a pair of tangled particles is applied, one of which is in "Property" casino, and the other works on the player. These particles are the main tools of the tote. The procedure for such: the player needs to open a box in which one of the particles may be, and detect it if it is present there. If the particles are not in the container, the player may require the organizer of the game to transfer it to the second particle to check it out in what condition it is. And if it turns out that the particle is in the changed state – different from which the player claimed the casino before the start of the game – the player wins. The system is designed to ensure equal distribution of the chances of winning and losing – after all, neither the player nor the casino will not benefit the unfair game in conditions where both parties can check each other at any time.
