A review of Bell inequality tests with neutral kaons
... by two spin–1/2 objects which is quite similar to the two–kaon state (1). In the Bohm singlet state, each spin–1/2 points both into any given spatial direction and its opposite one; similarly, each particle in (1) is both a kaon and an antikaon at the very same time. According to quantum mechanics, ...
