If there are two entangled particles separated by a distance and these are used for the quantum teleportation of a third particle, is the entanglement of two original entangled particles destroyed after this teleportation or can we use these again to transport another particle?

  • $\begingroup$ No-one has ever teleported any kind of particle. Only the state of the particle has been teleported. $\endgroup$ – Norbert Schuch Dec 8 '18 at 16:46
  • $\begingroup$ OK then after the state of a particle is teleported, does this destroy the entanglement of the particles that were used for the teleportation or can they be used again to teleport the state of another particle? $\endgroup$ – kishdude Dec 10 '18 at 21:20
  • $\begingroup$ Well, after the teleportation, the "target" particle carries the state of the particle which has been teleported, rather than the state it had before. $\endgroup$ – Norbert Schuch Dec 11 '18 at 11:01
