  We describe a scheme of stochastic implementations of quantum teleportation
and entanglement swapping in terms of neutral kaons. In this scheme, the kaon
whose state is to be teleported collides with one of the two entangled kaons in
an Einstein-Podolsky-Rosen state. Subsequent detection of the outgoing
particles of the collision completes the two-qubit projection on Alice side.
There appear novel features, which connects quantum information science with
fundamental laws of particle physics.
