• Abstract: We report on the possibility of teleportation of a quantum particle, a distinctly different phenomenon from the teleportation of a quantum state through entanglement. With the first meaning, teleportation is theoretically possible by placing the particle initially at rest (with a certain uncertainty) out of any equilibrium point of a potential well or barrier and by frequently monitoring whether the particle remains at rest. This quantum Zeno dynamics inhibits acceleration, and features disappearance from the classical turning point and appearance in other turning point, if there is any other, with a probability that approaches unity by increasing the frequency of the measurements. This phenomenon has all the ingredients attributed in science fiction to teleportation: The particle is always at rest, cannot be found in the path between the two turning points, and saves travel time. We discuss the feasibility, in principle, of teleportation of electrons, protons and other particles, and conclude its increasing impracticability as the particle gets heavier.

• Apparent teleportation of indistinguishable particles [0.0]
  Two teleportation-like phenomena were predicted by quantum mechanics: quantum teleportation and, recently, quantum particle teleportation. Here, we introduce the third teleportation-like phenomenon - apparent teleportation. It seems to be a natural consequence of the Standard Model's indistinguishable elementary particles and antiparticles.

  We propose a scheme to teleport a continuous variable optical qubit, encoded in an optical qumode, onto a discrete variable solid-state qubit, associated with a single nitrogen-vacancy center spin in diamond, via a hybrid entanglement. We find that the average teleportation fidelity can still exceed the classical limit, enabling substantial teleportation distances under realistic experimental conditions.

  In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates. We show that the onset of the Zeno regime is marked by a $textitcascade of transitions$ in the system dynamics as the measurement strength is increased.
